Ethernet network devices have their own space and importance in the network age. The real time operations demand the network devices with greater networking bandwidth as well as efficient network data processing. The major concern with the multiport network devices is the performance. Today's resource-intensive engineering and technology applications deals with the server virtualization, consolidation, high-volume data transactions and real-time technologies such as VoIP and video on demand. The operations requires the sufficient network bandwidth and CPU processing speed to process the data at a real time and this demand is continue to grow. The newer multiport hardware technologies provide performance improvements in virtualized server environments. But, hardware technologies having their own limitations in terms of power consumption, CPU utilization levels, latency and more importantly cost. This thesis will discuss some of the key software designs as well as configuration decisions, to facilitate multiport network devices to improve the performance over the existing infrastructure. This will provides the solutions such as symmetric network and Virtual LAN to overcome the hardware dependency and cost required to significantly improve the multiport network system performance over the current infrastructure. This improved performance includes bandwidth and CPU utilization under the heavy network loads.

In real many problems, most of criteria have interactive characteristics, which cannot be evaluated by additive measures exactly. For the human subjective evaluation processes it will be more better to apply Choquet and Sugeno integrals model together with the definition of 𝜆 − fuzzy measure, in which the property of additive is not necessary. This paper presents the application of fuzzy integrals as tool for criteria aggregation in the decision problems and evaluating medicine with illustrations of hierarchical structure of 𝜆 − Fuzzy measure for Choquet and Sugeno integrals model.

For the adoption of any new material or technology, it generally needs proven performance record over traditional materials. Considerable research is carried out in India, towards the technology development so that Self Compacting Concrete (SCC) could soon find a place in the Indian construction industry. In the present work, experimental investigation is carried out on the strength properties of fibrous SCC with triple blending. Fly ash and condensed silica fume (CSF) are both employed as replacement to cement at various percentages to give triple blending. By doing this kind of triple blending it is expected to derive the beneficial properties of both the mineral admixtures. Concrete mixture of grade M40 is designed and tried for the SCC. Steel fibres of different aspect ratios ranging from 10–20 are tried along with polypropylene fibres of 12 mm length. SCC mixtures with various combinations were tested for workability, compressive strength, split tensile strength and flexural strength. Comparisons are made. Based on the experimental investigation carried out in the present work, important and practically useful conclusions are drawn.

Constructed Wetland (CW) are efficient method in reducing the contaminants from wastewater but due to presence of insufficient oxygen inside CW bed which is one of the limiting factors of efficient treatment of wastewater.a lab scale model was developed to determine the performance of naturally aerated and artificially aerated CW both are planted with Typha latifolia.This study involves determining the efficiency of Typha latifolia in polishing pH, DO, conductivity and rate of plant growth. The performances of CW were evaluated after the first phase completion (underground water treatment and fully growth of plant). In second phase the domestic wastewater was supplied to treat at different HLR and OLR and evaluated the performance of CW. The CWs were constructed by using different media which consists of bed of aggregate, charcoal and broken bricks at different height. A special PVC pipe aeration system was provided in both CWs out of which one is connected to air pump for artificial aeration and other is open to atmosphere. For aeration PVC pipes was provided in the two layers i.e. between top and middle and middle and bottom of the media. The treatment performance of domestic wastewater was evaluated after the plant is fully grown. The result shows that artificial aeration increases the diffuse DO concentration in CWs and increases the growth of plant as compared to natural aeration CW.

One of the major components of a hydraulic structure is the turbine. The turbine plays a major role in converting the energy of falling water to mechanical energy that drives the electric generator. The choice of the right type of turbine will enhance the over-all performance of the system. This study evaluates and compares the performance of three Kaplan and three Propeller turbines to ascertain the best type of turbine for optimal operation of the system for small hydropower development of the River Ethiope. RETScreen small hydropower project software was used for the analysis of data on net head and design flow rate of the river. The result shows that for River Ethiope on a net head of 9.2 m and a design flow rate of 31.73 m3/s, the over-all energy delivered by the system is much higher with Kaplan turbine than the Propeller turbine and it is 90% efficient. Hence Kaplan turbine is recommended for the small hydropower development of the River Ethiope.

Multi-lingual multi-script often poses various challenges in handwritten numeral classification. In this paper, we present a method for classification of off-line handwritten numerals of three popular Indian scripts. Here we consider Kannada, Telugu and Tamil scripts for our experiment. The features used in the classifier are obtained from local intensity order patter descriptor. For feature computation, Local Intensity Order Pattern (LIOP) is used. Basically LIOP encodes the local ordinal information of each pixel and the overall ordinal information is used to divide the local patch into sub-regions which are used for accumulating the LIOPs respectively. Therefore, both local and overall intensity ordinal information of the local patch are captured by the LIOP descriptor so as to make it a highly discriminative descriptor. LIOP descriptor features are not only invariant to monotonic intensity changes, image rotation but to many other geometric and photometric transformations such as viewpoint change, image blur issues are effectively addressed in our experiments [7]. A five-fold cross validation technique with numeral network classifier has been used for result computation and we obtained 98.34%, 98.40%, and 97.51% accuracy for Kannada, Telugu, and Tamil scripts respectively.

A smart stick has been built for the visually impaired people that help to detect obstacles with the use of infrared, ultrasonic and water sensors. Obstacles within the distance of about 3m can be detected with the help of these sensors. Also, we make use of GPS module to give positioning and navigation to the stick. Using GPS module assists the blind person to reach his destination. While the blind person navigate, the GPS receiver gets the location of the person updated and the co-ordinates of that location can be used to keep track of the blind person for safety concerns. The blind person can also send emergency message or make an emergency call at times of risk, to his guardian, using GSM module. In this way, the GSM module will be used to give notifications when the blind person has threats.

The challenges associated with teaching undergraduate Mathematics will be discussed: Negative attitudes of students to Mathematics, Student‟s reluctance to practice Mathematics, and surface learning. Some (or all) of the ways in which assessment can be used to address these challenges will be discussed. If strategically used, assessment methods/tasks can enhance the teaching and learning of mathematics. Some of the unique challenges that we as lecturers face in teaching mathematics can be remedied by selecting appropriate assessment techniques/tasks. Using the tutorial time fruitfully is one of the challenging aspects in teaching mathematics. Not taking tutorials and other formative assessments seriously is not an uncommon student attitude in higher education contexts (Baderin, 2005, Pope, 2001, Smyth, 2004). Students who are pressured for time often do not see the immediate value of formative assessment or of discussion as a useful learning activity (Baderin, 2005). The purpose of introducing the assessment method, implementation method, its advantages, and disadvantages will be examined. A reflection on the assessment method and concluding remarks will be provided.

Presented in this paper is a result of an experimental study for assessing the development performance of a high strength headed reinforcing bar which is vertically jointed along the axial direction to a reinforced concrete member, by assuming the development length of headed reinforcement, distance between the centers of each head, existence of hoop, etc. The result showed that the longer the development length, the higher the maximum strength, while the center-to-center distance between heads did not significantly affect the maximum strength. The maximum strength of a test subject which is equipped with hoops around the headed reinforcement is 86.0% higher than that of another subject which is not prepared with hoops, proving that the confinement details of the headed reinforcement are of paramount importance. While the theoretical strength derived from the CCD method underestimates the experimental strength, a theoretical strength estimated by using the ACI 318-11 development length formula assesses the experimental strength as unsafe.

Now-a-days many services get delayed due to traffic jams especially in large cities. Ambulance service is one of the crucial services that gets delayed. Sometimes on-sight doctors are not available, so the patient does not get medical attention immediately. To overcome this situation this paper describes a solution that is 'Intelligent Ambulance with Traffic Control' wich includes a traffic control system as well as a health monitoring system. In health monitoring system, the patient's vital health parameters such as ECG, Heart Rate and Body Temperature are monitored. For ECG measurement, a 2-lead Electrode Electrocardiogram technique is used. Heart Rate measurement is done using photoplethysmography method. LM-35 is used to measure the patient's body temperature. These parameters are sent to a PC in ambulance via serial communication and this data will be sent to the hospital server. In traffic control system an RF transmitter on the ambulance will communicate with the RF receiver mounted on the signal post. An algorithm is used to control the traffic signals automatically based on the key pressed by the driver from keyboard in the ambulance. The information reading the current as well as future location of ambulance, is sent from the ambulance itself. This information is used to optimally control the traffic.

Concrete is a macro-material strongly influenced by its nano-properties.The addition of nano-silica (SiO2) to cement based materials can control the degradation of the calcium-silicatehydrate reaction caused by calcium leaching in water, blocking water penetration and leading to improvements in durability (Mann, 2006).Nano-sensors have a great potential to be used in concrete structures for quality control and durability monitoring. (to measure concrete density and viscosity, to monitor concrete curing and to measure shrinkage or temperature, moisture, chlorine concentration, pH, carbon dioxide, stresses, reinforcement corrosion or vibration).Carbon nanotubes increase the compressive strength of cement mortar specimens and change their electrical properties which can be used for health monitoring and damage detection.The addition of small amounts (1%) of carbon nanotubes can improve the mechanical properties of mixture samples of portland cement and water. Oxidized multi-walled nanotubes show the best improvements both in compressive strength and flexural strength compared to the reference samples.

In continuous technological development, an automotive industry has increased the demand for high efficiency engines. A high efficiency engines is not only based on its performance but also for better fuel economy and less emission rate. Researches in heat transfer have been carried out over the previous several decades, leading to the development of the currently used heat transfer enhancement techniques. Radiator is one of the important parts of the internal combustion engine cooling system. So improving the performance and reducing cost of radiator is the necessary research. For higher cooling capacity of radiator, addition of fins is one of the approaches to increase the cooling rate of the radiator. The water and ethylene glycol as conventional coolant have been widely used in an automotive radiator in many years. With the advancement of nanotechnology, a coolant are invented which is known as "nanofluids". The Researchers found that these fluids offer higher thermal conductivity compared to that of conventional coolants. With these specific characteristics, the size and weight of an automotive car radiator can be reduced without affecting its heat transfer performance. An automotive radiator (Wavy and Louvered fin type) model is modeled on modeling software CATIA V5 and performance evaluation is done on pre-processing software ANSYS 14.0. Present study outline that the use of fins and nano fluid may improve the performance of automotive radiator. Results have shown that the rate of heat transfer is better when nano fluid (Si C + water) is used as coolant, than the conventional coolant.

There is an extensive class of Web applications that involve predicting user responses to options. Such a facility is called a recommendation system. A specific example of recommendation systems is to offer customers a non-line retailer suggestions about what they might like to buy, based on past history of purchases and/ or product searches. Cold start is a potential problem in computer-based information systems which involve a degree of automated data modeling. Specifically, it concerns the issue that the system cannot draw any inferences for users or items about which it has not yet gathered sufficient information. The cold start problem is most prevalent in recommender systems. Typically, are commander system compares the user's profile to some reference characteristics. These characteristics may be from the information item (the content-based approach) or the user's social environment (the collaborative filtering approach). Preference elicitation is a decision support system capable of generating recommendations to a user, thus assisting in decision making. It gives preferences accurately, finds hidden preferences and avoids redundancy.

The feeder reconfiguration problem highly nonlinear with multi objective and multiple constrains. It chooses the on/off status of the switches in a distribution network in order to meet one or more objective such as power loss or cost or voltage regulation. It is a mixed-integer nonlinear program and, hence, hard to solve. We proposed an iterative algorithm using ETAP 12 In this paper which follows an ac optimal power flow problem. The algorithm is computationally efficient and scales linearly with the number of redundant lines. It requires neither parameter tuning nor initialization for different networks. It successfully computes an optimal configuration on all four networks we have tested. Problem reduces the losses by 5% compare to the existing methods and improve the voltage regulation. Even during contingencies, the voltage regulation is better and losses are less compare to the conventional methods.
