Effect of Grading Policy on Students' CGPA−A Case Study of an Engineering College
  • Abstract
  • Keywords
  • Reference
  • Full Article
This study investigates the effect of change in grading policy on students Cumulative Grade Point Averages (CGPAs). The impact of two grading policies, a lenient grading policy versus a strict grading policy, was studied through the actual CGPAs of the students of an engineering college in Pakistan. The lenient grading policy contains 5 grades (A, B, C, D, F) whereas the strict grading policy contains 7 letter grades (A, B+, B, C+, C, D, F). A sample of 1578 students CGPAs, divided in two sections, was analyzed for this purpose in which almost half of the students obtained CGPAs on lenient grading policy and the other half on strict grading policy. Motivating students to perform better is one of the expected functions of grading policy. Results show that strict grading policy has a statistically positive impact on student CGPAs, when compared to the student CGPAs on lenient grading policy. The low-performers get more benefit than the high-performers in terms of CGPA when the stricter grading policy is employed.

Process Optimization of a Local Steel bar Manufacturing Firm Using SPC and ANOVA

  • Abstract
  • Keywords
  • Reference
  • Full Article
In a steel bar manufacturing industry, identification of significant factors which affect the process efficiency is of prime importance to achieve maximum yield. In the undertaken research study, reheating furnace temperature of 1050 ᴼC of a local steel bar manufacturing facility of Peshawar, Pakistan is found to be statistically significant with the help of analysis of variance (ANOVA) experimentation. The second analysed temperature level is 900 ᴼC which comes out to be insignificant. At 1050 ᴼC temperature, minimum production scrap is found and z. bench quality standard is also improved. For yield strength quality characteristic of the product the scrap level is 90% less than the production at 900 ᴼC while the z. bench level is improved to 28%. At same temperature of 1050 ᴼC, production scrap is reduced over 42% and z. bench is improved to 11% for ultimate tensile strength quality characteristic. 1050 ᴼC temperature of the reheating furnace of the steel bar manufacturing process is statistically found to be optimum temperature level of production.

Power Quality Enhancement using Different "FACTS" Devices.
  • Abstract
  • Keywords
  • Reference
  • Full Article
Improvement of Power Quality has a positive impact on sustained profitability of the distribution utility on the one hand and customer satisfaction on the other. Flexible AC Transmission Systems (FACTS) controllers have been used in power systems since the 1970s with the objective of improving system dynamic performance. Power quality is an issue that is becoming increasingly important to electricity consumers at all levels of usage. Sensitive power electronic equipment and non-linear loads are widely used in industrial, commercial and domestic applications leading to distortion in voltage and current waveforms. Due to the environmental, right-of-way, and cost problems in both bundled and unbundled power systems, many transmission lines have been forced to operate at almost their full capacities worldwide. FACTS controllers enhance the static performance viz. increased loading, congestion management, reduced system loss, economic operation, etc., and dynamic performance viz. increased stability limits, damping of power system oscillation, etc. In this paper, an overview of FACTS controllers is explained. Various FACTS controller several devices in FACTS family are also discussed.

Design of Stepped Impedance Microstrip Low Pass Filter with DGS
  • Abstract
  • Keywords
  • Reference
  • Full Article
A design of Butterworth stepped impedance microstrip low pass filter with DGS is presented in this paper. Two designs are introduced. The first design is a seven order low pass filter with three interdigital slots with different finger lengths inserted under the position of high impedance lines. The maximum insertion loss in the passband is better than 0.97 dB and the maximum group delay variation within the passband is less than 10 ps. The other design is a nine order low pass filter that use different shapes of the DGS (rectangular, square dumbbell and interdigital). The maximum insertion loss is about 0.5 dB and maximum group delay variation is 27 ps. The cutoff frequency of the proposed two designs is 16 GHz. The filter used for LEO satellite application. The filter is analysed using CST Microwave Studio, IE3D zeland and ADS. The filter is fabricated with photolithographic technique and scattering parameters are measured by using Vector Network Analyzer. Measurements and simulations show good agreement.

Ranking Spatial Data by Quality Preferences
  • Abstract
  • Keywords
  • Reference
  • Full Article
The objects in real world can be ranked based on the features in their spatial neighborhood using a preference based top-k special query. In this paper, a two purpose query structure for satisfying the user requirements is implemented. For example, a user who wishes to find a hotel with 3 star categories that serves sea food which provides the nearest airport facility. This concept can be obtained by developing a system that takes a particular query as the input and displays a ranked set of top k best objects that satisfy user requirements. For that, an indexing technique R-tree and a search method BB algorithm for efficiently processing top-k spatial preference query is used. R-tree (Real-tree), a data structure is the first index specifically designed to handle multidimensional extended objects and branch and bound (BB) algorithm that makes searching easier, faster and
accurate. The key idea is to compute upper bound scores for non-leaf entries in the object tree, and prunes those that cannot lead to better results. The advantage of using this algorithm is that it can reduce the number of steps to be examined.

Future Scope Analysis of Distributed Generation in Deregulated Indian Power Market

  • Abstract
  • Keywords
  • Reference
  • Full Article
Till date, greater chunk of electricity is generated in conventional way at large generating stations, after that electricity is transmitted at high voltages to the load centres and then it is distributed among consumers at distribution level voltage through distribution systems. Whereas Distributed Generation is defined as generation located at or near the load centres.The liberalization of the electricity market and the separation between electricity supplier and network operator in India have gained attention to the subject of connecting generated power by distributed generation plants directly to grids. There are many reasons why a customer may choose to install a distributed generator, as it can be used to generate a customer's entire electricity supply or for peak shaving or for standby or emergency generation or as a green power source (using renewable technology). In some remote locations, DG can be less costly as it eliminates the need for expensive construction of distribution and/or transmission lines. The objective of this paper is to assess the impact and study the future scope of Distributed Generation on the deregulated power market scenario in India using Herfindahl Index.

  • Full Article
Glass samples of the Lithium borosilicate were prepared by conventional melt-quench technique. The density and molar volume of some silicate glasses were determined in order to study their structure. Molar volume decreases linearly as mole % of SiO2 increases. The physical parameters like Oxygen packing density, Ionic concentration, Inter ionic distance, Polaron radius, Dielectric constant, Reflection loss, Band energy gap, Refractive index, Molar refractivity, Molar polarizability, Metallization, Electronic polarizability and Conductivity are studied. Oxygen packing density is decreasing with increasing the concentration of SiO2. Ionic concentration increases, where as inter ionic distance, polaron radius, decreases with increasing the concentration of SiO2. Molar polarizability, Molar refractivity, Electronic polarizability varies alike with increasing mole % of SiO2 respectively. Maximum values at 5 mol % of SiO2 are 7.671 *1024ions/cm3, 19.348 cm3 and 0.33*1024 ions/cm3. Electronic polarizability, Reflection loss are varies similarly while Metallization is exactly opposite to them; at 5 mol % of SiO2 Reflection loss is 0.359 and Metallization is 0.166.Conductivity increases according to glass transition temperature. Mole % of SiO2 and ionic concentration varies linearly with slope 0.0222, intercept 10.9 and R2 0.999. Other linear variations are also studied.

  • Full Article
In recent years mobile ad hoc networks have become very popular and lots of research is being done on different aspects of MANET. Mobile Ad Hoc Networks (MANET)-a system of mobile nodes (laptops, sensors, etc.) interfacing without the assistance of centralized infrastructure (access points, bridges, etc.). There are different aspects which are taken for research like routing, synchronization, power consumption, bandwidth considerations etc. This paper concentrates on routing techniques which is the most challenging issue due to the dynamic topology of ad hoc networks. There are different strategies proposed for efficient routing which claimed to provide improved performance. There are different routing protocols proposed for MANETs which makes it quite difficult to determine which protocol is suitable for different network conditions .This paper provides an overview of different routing protocols proposed in literature and also provides a comparison between them.

Handling Selfishness in Replica Allocation over a Mobile Ad Hoc Network for improving data accessibility

  • Abstract
  • Keywords
  • Reference
  • Full Article
In a mobile ad hoc network, the mobility and resource constraints of mobile nodes lead to network partitioning. Several data replication techniques have been proposed to minimize network partitioning. All mobile nodes collaborate fully in terms of sharing their memory space. In reality, some nodes may selfishly decide only to cooperate partially with other nodes. The nodes which act selfishly to conserve their memory space are called selfish nodes.To over come these selfish nodes selfish node detection algorithm has been used which uses two techniques known as partial selfishness and novel replication allocation technique.

Effect of Focus on the Intensity of Disyllabic Words in Chinese

  • Abstract
  • Keywords
  • Reference
  • Full Article
In this experiment, the intensity pattern and the effect of focus on it for disyllabic words in Chinese is analyzed. Results show that, in most cases, the average intensity of rhyme in the first syllable is comparatively great, while for the onset, due to intervocalic voicing, that in the second syllable is great. Focus has great effect on intensity. Under focused condition, the overall intensity will greatly increase. The results from this study will be useful in speech engineering.

Simulations of mobile radio systems require propagation models for determining the channel characteristics for a given arbitrary scenario. Propagation path loss models can be used to predict wireless channel characteristics like received signal strength, multipath effects, and interference. These predictions are an important aspect of simulation of wireless networks and aid in the high-level network planning process. Various models are available for modeling propagation characteristics and they vary in terms of both modeling performance and computational complexity. Propagation path loss models can be used to predict wireless channel characteristics like received signal strength, multipath effects, and interference. This paper includes the discussion on next generation networks and propagation models in NS3.

In hydro generator breakage of pressing finger is major problem generally occurs due to surface crack on pressing fingers. Surface crack propagation leads break down of hydro generator. Break down of hydro generator increase maintenance cost and time. It also leads replacement of existing generator. Replacement of hydro generator is so costly because cost of one generator is approximately one cror rupees.it also disrupts production of electricity. Now days Dye Penetration Testing (DPT)apply for testing surface crack which was the root cause of breakdown of hydro generator. This Non Destructive Testing (NDT) detect surface crack of pressing fingers. After applying DPT on pressing fingers apply statistical analysis of samples of its and then control chart also applies on fingers which give result in terms of acceptance or rejection of its.Acceptence sample goes forward in operation and other samples reject.

The Influence of Carrier Blend Proportion and Flavor Load on Physical Characteristics of Nutmeg (Myristica frangrans Houtt.) Essential Oil Microencapsulated by Spray Drying

  • Abstract
  • Keywords
  • Reference
  • Full Article
The effect of proportion of maltodextrin and gum arabic as carrier material and the percentage of nutmeg essential oil as flavor load on microencapsulation by spray drying was studied. The proportions of 0, 20, 40 and 60 percent gum arabic (w/w) in the carrier blend and 10, 20 and 30 percent nutmeg oil (w/w) as flavor load were studied. Emulsions were microencapsulated in a vertical co-current spray drier equipped with a rotary wheel atomizer operated at 18000 rpm. The inlet air temperature was set at 180 ± 2oC. The microcapsules formed were then analyzed for their physical characteristics. Flavor load was found to have no influence whereas blend proportion was found to influence the moisture content. True density increased until 40% gum arabic and decreased thereafter. Solubility increased with increase in flavor load and blend ratio. Though the highest encapsulation efficiency of 70.1% was obtained at a flavor loading of 10% at a carrier proportion of 40% gum arabic, further decrease was marginal with increase in flavor load up to 20%. Considering the product characteristics, a 40% gum arabic in the carrier blend and a flavor loading of 20% nutmeg oil were found to be optimum. The micrographs of optimum combination showed uniform spherical powder with surface dents and a central void with microdrops distributed in the solid matrix.

  • Full Article
Many efficient algorithms and architectures for the design of low-complexity bit-parallel Multiple Constant Multiplications (MCM) operation that dominates the complexity of Digital Signal Processing (DSP) systems. On the other hand, digit-serial architectures offer alternative low-complexity designs, since digit-serial operators occupy less area and are independent of the data word length. This paper introduces the problem of designing a digit-serial MCM operation with minimal area at gate-level and presents the exact formalization of the area optimization problem In this paper, we address the problem of optimizing the area using multiple constant multiplier, design architecture. The proposed optimization algorithm is used in the design of digit-serial finite impulse response filters that will yield better performance, with high efficiency.

The use of Electronic Length Frequency Analysis computer program for age, growth and management assessment of Mugilidae Liza falcipinnis (Linné, 1758) from Ebrié and
Grand-Lahou lagoons, Ivory Coast.

  • Abstract

  • Full Article
Age, growth, mortality and exploitation status of Liza falcipinnis were studied in Ebrié and Grand- Lahou lagoons, Ivory Coast from January 2006 to December 2007. A total of 2162 specimens were examined (914 and 1248 in Ebrié and Grand-Lahou lagoons respectively). Monthly length frequency data were analyzed by FiSAT software for estimation of population parameters. Asymptotic length (L∞) was 39.9 and 42.0 cm for Ebrié and Grand-Lahou lagoons respectively. Growth coefficient (K) was 0.36 year-1 and 0.20 year-1 respectively in Ebrié and Grand-Lahou lagoons, and the calculated growth performance index (φ') was 2.76 and 2.59 for Ebrié and Grand-Lahou lagoons respectively. Total mortality (Z) by length-converted catch curve was estimated at 1.28 year-1 and 1.43 year-1 respectively in Ebrié and Grand-Lahou lagoons, fishing mortality (F) at 0.46 year-1 and 0.53 year-1, and natural mortality (M) at 0.82 year-1 and 0.90 year-1 respectively in Ebrié and
Grand-Lahou lagoons The exploitation level (E) was estimated to be 0.36 and 0.37 in Ebrié and Grand-Lahou
lagoons respectively. The recruitment pattern was continuous with two major peaks event per year. The
exploitation level (E = 0.36 and 0.37 < 0.50) and lower fishing mortality (0.46 year-1 and 0.53 year-1) indicate
that the Liza falcipinnis stock is under-exploited. Wherever, the majority of fish caught in the both lagoons at a
size far below the first sexual length. This suggests for management purpose and conservation the reproducing
part in the both lagoons.

Laminated composite materials are being increasingly used in various engineering applications due to high specific strength, stiffness, low weight and corrosion resistance. These materials are selected for weight critical application due to good rating as per the fatigue failure is concerned. This investigation utilizes the suitable test-rig which is capable of generating data related to dynamic failure behaviour of laminated composite specimens. The experimental data generated from the test rig is analysed to understand the failure behaviour of laminated composites of carbon/ epoxy. The flexural fatigue tests are conducted to obtain stiffness degradation curves to interpret the failure behaviour. This paper explicitly discus and presents the influence of orientation sequence of stacking subjected to flexural fatigue. The fatigue failure process is presented in terms of the stiffness degradation verses number of load cycles.

Performance Analysis of Fused Eye Vein and Finger Vein Multimodal Biometric System

  • Abstract
  • Keywords
  • Reference
  • Full Article
In recent years, biometric authentication has become one of the popular strategy for various applications like ATMs, online banking, e-commerce websites etc., New biometric modalities are currently being tested and implemented. In this paper, a relatively new paradigm using fusion of biometric images eye vein and finger vein is proposed. Though different multimodalities exist this combination is unique and gives promising results and hence can be considered in future as a positive biometric trait. The proposed approach is based on the fusion of the two traits by extracting independent feature pointsets from the two modalities and making them compatible for concatenation. The concatenated feature pointset has better discrimination power than the individual feature vectors. The proposed eye vein and finger vein fused template was evaluated using publicly available UBIRIS, IUPUI and SDUMLA-HMT multi wavelength database. The experimental results show that this technique is efficient and provides accurate identity verification than other biometric traits.

Day by day the use of sophisticated electronic devices is increased. Unfortunately these devices are very sensitive to power quality disturbances. Power quality disturbances is an occurrence manifested as a nonstandard voltage, current, or frequency that results in tripping or failure of end use equipments. One of the major problems dealt here are power sag/swell. To solve this problem custom devices are used. Among these, the distribution static compensator, dynamic voltage restorer and unified power quality conditioner which are based on the VSC principle are used for power quality improvement. This paper mainly proposes a new connection for a interline unified power quality conditioner (IUPQC) to improve the power quality between two feeders in a distribution system. The proposed configuration of the UPQC is developed and verified for various Power quality disturbances by simulating the model using MATLB/SIMULINK.

Car Automation Using Controller Area Network

  • Abstract

  • Reference
  • Full Article
Based on requirements of modern vehicle, in- vehicle Controller Area Network (CAN) architecture has been implemented. In order to reduce point to point wiring harness in vehicle automation, CAN is suggested as a means for data communication within the vehicle environment. The benefits of CAN bus based network over traditional point to point schemes will offer increased flexibility and expandability for future technology insertions.
This paper describes system which uses sensors to measure various parameters of the car like speed, distance from the other car, presence of alcohol in car and accidental change of lane and sends a warning signal to the driver if any of the parameter goes out of range to avoid accidents and breakdown of car . In addition to this if accident occurs in any remote area then using bump sensor accident is detected and SMS is send immediately using GSM. Also temperature and pressure sensors are implemented to check engine's temperature and fuel pressure for regular maintenance. A situation that provides a good example of how the system works is when a driver is about to change lanes, and there is a car in his blind spot. The sensors will detect that car and inform the driver before he starts turning, preventing him from potentially getting into a serious accident.

  • Abstract
  • Keywords
  • Reference
  • Full Article
Hausmannite, Mn3O4, nanoparticles were synthesized successfully via combustion synthesis route with MnCl2.4H2O as manganese source. The samples were characterized to find the structural, functional and magnetic properties by XRD, FT-IR, FT-Raman and VSM respectively. An attempt is made to summarize the detailed field dependent magnetization study of the synthesized material is presented. Structural studies by XRD indicate that the synthesized material as tetragonal crystal structure with size 35nm. FT-IR and FT-Raman analysis revealed stretching vibrations of metal ions in tetrahedral and octahedral co-ordination confirming the crystal structure. Magnetic studies of the as synthesized sample depict paramagnetic behaviour at room temperature. The superparamagnetic behaviour was observed at room temperature with no saturation magnetization and hysteresis in the region of measured field strength. These measurements as a function of temperature and field strength showed a reduction in ferrimagnetic temperature Tc = 41K as compared to those reported for the bulk Tc = 43K.

This paper presents the DSTATCOM topology for compensation of AC and DC loads. The DC loads are supplied through inverter DC link due to these loads capacitor voltages will get distorted. In this the algorithm instantaneous symmetrical components used to extract positive sequence of supply voltage to generate reference compensator currents under unbalance and non stiff supply voltages. Its state space model is presented and state matrix components have been developed considering unbalance non stiff source. The voltage source inverter has operated in current controlled mode, switching pulses for the filter have been developed using two level and three level hysteresis controller. Examined the proposed theory under transient conditions using two level and three level Hysteresis Current Controller (HCC). It is observed in the three level hysteresis current controller variation of DC capacitor voltages are less under transient conditions. This is because of in three level hysteresis controller, inverter switching strategies uses inverter zero output condition. The simulations have done in MAT LAB to validate the proposed ideas.
