On The Behavior of Strategies in Iterated Games Between Relatives[ ]


The theory of iterated games provide a system framework to explore the players' relationship in a long-term. In this paper we consider the iterated prisoner's dilemma game (IPD) played between relatives . Two state automata are used to play infinitely iterated the two players where each action can be mis-implemented with small error probability. the payoff matrix using the perturbation approach is computed . Using a different values of the average relatedness between players and different values of the payoff variables (R; S; T; P) , the behavior of strategies for iterated prisoner's dilemma game in each situation is studied .

Performance Evaluation of Novel Energy Efficient Water Cooler[ ]


The continuously increasing imbalance between the energy demand and supply, together with escalating cost of the conventional energy resources as well as growing environmental pollution are forcing people to invent newer methods either to reduce energy demands or to find alternative energy resources. In refrigeration and air- conditioning systems, the compressor is the largest consumer of electricity, in most of the cases consuming about 70% of total electricity. It is well known fact that water cooling is always effective than air cooling. Water cooler provides an opportunity to use water cooled condenser being always installed near water source. An in-house facility is developed by modifying the existing water cooler system to use the water as cooling medium instead of the air as cooling medium. Accordingly, a water cooled condenser system is designed and developed for existing water cooler with the facility to use of waste water from the water cooler, available relatively at low temperature in significant amount. Experiments were conducted at various operating conditions. It is observed that the COP is higher with water cooled condenser in comparison with air cooled condenser due to saving in power. However, cooling capacity is obtained low for water cooled condenser due to reduction in condenser pressure. High flow rate of cooling water in water cooled condenser system gives better performance when compared to low and medium flow rates of cooling water at condenser. High flow rate of cooling water offer better performance at the cost of water. Waste water utilization of the water cooler with low flow rate brings the system COP almost similar to medium flow which saves the water.

Securing and Authenticating Access to Encrypted Cloud Data[ ]


Sensitive information, when placed in wrong hands may lead to unwanted results. One way of protecting your data is to never use a cloud based service, but it carries dis-advantages of its own. So, how could it be possible to actually trust the cloud service provider with your sensitive information, without actually giving away the key to access your information?

Constant Market Share Analysis for Exports of Pakistan: Case of Developed Market Economies[ ]


This Paper investigates Pakistan`s exports to Developed Market Economies (DMEs) for the period 2003-12 using the Constant Market Share analysis. CMS decomposed the total export`s growth in to four major components. i.e. the world trade effect, the commodity composition effect, the market distribution effect and the competitiveness effect. HS 4 digits panel data on yearly basis has been used in the study which has been collected by the International Trade Centre (ITC). The study shows that Pakistan has the potential to increase its exports to the DMEs, but targeted diversification is required with respect to commodities and Pakistan’s exports are competitive in the DMEs..

Privacy Preservation of Cloud Storage Data using Classification[ ]


Privacy Preserving Data Mining (PPDM) addresses the problem of developing accurate models about aggregated data without access to precise information in individual data record. Under the single trust level assumption, a data owner generates only one perturbed copy of its data with a fixed amount of uncertainty. This assumption is limited in various applications where a data owner trusts the data miners at different levels. Multilevel Trust (MLT) poses new challenges for perturbation-based PPDM. In contrast to the single-level trust scenario where only one perturbed copy is released, now multiple differently perturbed copies of the same data are available to data miners at different trusted levels. The more trusted a data miner is the less perturbed copy it can access; it may also have access to the perturbed copies available at lower trust levels. Moreover, a data miner could access multiple perturbed copies through various other means, e.g., accidental leakage or colluding with others. Here a new and efficient technique for privacy preservation is implemented for the cloud so that various security issues in the cloud is detected and prevented.

Optimization of EDM Process by new Carbon Black Layer Technology and Comparison with Traditional Regression Analysis Method[ ]


It is method in which the metals like has talloy, nitralloy, nimonics etc. are such that they can't be machined by conventional methods but require some special techniques. In this paper there is a optimization of characteristics of EDM like Material removal rate, tool wear ratio and surface roughness by using different input parameters like ram speed, current intensity, pulse duration and duty factor. To optimize the EDM process, the fractional factorial method developed by Taguchi, which is a traditional technique that allows a process to be optimized using relatively few experiments when there are large No. of input variables, are used. By traditional method, as result we find out the highest MRR value obtained is (1) 98 mm3/min; the TWR at these setting 0.5% and the surface roughness (Ra) is 9.4 µm. (2) The lowest TWR obtained is 0.16%, the values of MRR is 17 mm3/min and Ra is 5.8 µm. (3) The lowest Ra is 4.6 µm, the MRR and TWR values for these settings are 28 mm3/min & 3.5%. So these results confirms that there is no single set of input parameter settings which optimize all three output parameters. If it is essential to have as smooth a surface finish as possible, then a very low MRR and a very high TWR would be obtained. In new method, there is an improvement in TWR. The mean value in the improvement is (60±16%) to 95% significant. The MRR appears to increase slightly for a preprocessing depth of 0.025 mm but decreases there after so the results confirm the theory that the TWR in improved by the preprocessing method. It can been seen that there is an improvement in all cases. The mean value of the ratio is 1.39 ± 0.9 (95% confidence limit). There is, however, no significant correlation between pulse duration and TWR improvement. The MRR was largely unchanged for the 1 mm preprocessing depth, but was reduced for the 4 mm depth. So we can conclude that the improvement in TWR was due to influence of migrated carbon in new method.

Comparative Performance Analysis of AODV, DSDV and DSR for Wireless Devices[ ]


Routing is the task of directing data packets from a source node to a given destination. The On-demand protocol performs better than the table-driven protocol.In this project we have analyzed and compared three routing protocols i.e. AODV, DSR, DSDV implemented in ns-2. The protocols are simulated in a wireless environment with routing protocols and varying pause time in a simulation environment of 100 nodes. We investigated the performance metrics namely Packet Delivery Ratio (PDR), Average end-to-end delay, energy spent and throughput through NS-2 simulation. The performance of protocol is one of the interesting issue.

An Experimental Study on Compressive Strength of Various Cement Concrete Under Sea Water[ ]


Potable water is becoming a scarce commodity on this planet Earth with time. Hence, we need to find alternatives for potable water as billons of liters of water is used in construction industry. This research work seeks to investigate the use of sea water as mixing and curing of concrete as 97% of the water on Earth surface is sea water. For this concrete cubes were cast for a design mix of M-20, 1:1.777:2.826 by weight and 0.47 water cement ratio and M-25, 1:1.432:2.472 by weight and 0.414 water cement ratio using OPC 43 grade, OPC 53 grade and PPC cement as per guidelines for concrete mix proportioning with a slump of 75 mm to 100 mm. Half of the cubes were cast and cured with potable water and half with sea water. The cubes were cast and cured for 7, 14, 21, 28 days and was tested for compressive strength. From the results it was found that compressive strength increases during initial days of curing when cubes are cast and cured in sea water but finally characteristic strength decreases by about 5% as compared to cubes cast and cured with potable water.

An Evaluation of the Capacity of two Roundabouts: A Case Study of Agartala, Tripura[ ]


Roundabouts are one of the biggest areas in road intersection. The special form of at-grade intersection is roundabout which is laid out for the movement of traffic in one direction. In urban area, total quantity of vehicles increase very sharply. Quantities of vehicles are also increasing at the intersection of post office chowmuhani area as well as circuit house area in Agartala, Tripura. With this increasing rate of vehicles may cause congestion, delay and accident in intersection. The study shows that the Post office chowmuhani and in Circuit House chowmuhani roundabouts the total traffic capacity is 3599 PCU/hour and 2970 PCU/hour respectively. Hence, as per the study it expected that the Circuit House chowmuhani roundabout will be collapsed by the year 2022.

The Manobo Tribe Then and Now:An Ethnography[ ]


The study delved into the cultural practices of Agusan Manobo tribe in the past as it is practiced in the present. It also sought the strategies used by the tribe to withhold their practices as well as their hopes and aspiration. The study made use of the interview to the selected ten elders of the tribe and conducted also a focused group discussion to the seven datus surrounding Sitio Kapda, Barangay Sabud, Loreto, Agusan del Sur, Philippines. It is revealed in the study that rituals, belief in the spirits, marriages, healing, settling disputes, burials and choosing new leader were the practices of the tribe. As pious people, their activities are always consulted with unseen spirits to whom they believed to have interference of every activity of human being. It is revealed that the oral tradition was the most common way of conveying their practices to the young so that it will continue to exist. The family was the first venue of such witnessing of practice. They believed in the unity and faith of the tribe in order to continue their practices. It made known from the study that the tribe longed for indigenous education for their young to use when they led the tribe in the future. They wanted also that they have their own land to live where the next generation can exercise their beliefs and practice their rituals. It went out also that they wanted their culture to be written as part of the history.

Hospital Engineering and Infection Control[ ]


The hospital design has an important role in the control of hospital associated infection. The physical design of hospital is an essential component of a hospital’s infection control strategy, incorporating infection control issues to minimise the risk of infection transmission. Hospital design therefore, needs to consider the separation of dirty and clean areas, adequate ventilation, lighting and storage facilities and design of patient accommodation areas, including adequate number of wash hand basins and single bed facilities. However, there is inherent difficulty in establishing this fact because of too many confounding factors in the form of type of patients, number and type of man power available in the facility, the policies and procedures and other resources used. These factors cannot remain constant. A review of various studies and guidelines available on the subject was undertaken. It is concluded that the hospital design does matter for infection control.

Recent trends towards multi-focus image fusion techniques[ ]


Image fusion finds application in an exceedingly wide selection of areas involving image processing. It is just a mechanism to improve the grade of information from a group of images. The primary objective of image fusion would be to generate a fused image that gives the complete and consistent data. The resultant image is formed by combining such magnified information from the input images right into a single image. The typical objective of the paper has gone to explore various applications of image fusion and the various methods for efficiently fusing digital images. It's been found that many the prevailing researchers have neglected many issues; i.e. no technique is accurate for different sort of circumstances. This paper eventually ends up with suitable future directions which can increase the performance of image fusion than existing techniques.

Lipid analysis of tissues from camel (Camelus dromedaries) reveals unique composition in fatty acids[ ]


Domesticated Arabian camel, Camelus dromedarius, is the most important animal in arid and semiarid areas, as it represents the main source of meat, milk and fat besides its high cultural and economical values. The present work was carried out to determine the compositions of fatty acids and phospholipids in the hump, plasma and liver mitochondria were studied under various physiological and nutritional conditions of this ruminant. In plasma, palmitic (C16:00), linoleic (C18:2 n-6), stearic (C18:00) and oleic (C18:1 n-9) acids represent 70% of the fatty acids identified. In liver mitochondria, a closely similar ratio was obtained (62%) but with different proportions. In the hump, palmitic, oleic, stearic and myristic acids represent 82% of the total fatty acids. Moreover, qualitative differences were observed with myristic (C14:00) acid whereas linoleic acid was lacking. The phosphatidylcholine and phosphatidylethanolamine are the major mitochondrial phospholipids with (62%) whereas sphingomyelin represent (14%), while phosphatidylinositol shows the weakest rate (5%). The composition of fatty acids (chain length and unsaturation) in plasma and in liver mitochondria did not depend on age, sex, mass and diet. These results shows qualitative similarity in the composition of fatty acids between plasma and liver mitochondrial membranes but not with in the hump. These results suggest that the camel developed a particular metabolic regulatory system to maintain constant the composition of fatty acids independently of physiological and the nutritional conditions.

Antihyperglycemic potential of urticol from Urtica dioica leaves using freshly isolated rat hepatocytes[ ]


The present study investigated the potential upregulation of glucose absorption in primary rat hepatocytes by compounds from Urtica dioica leaves (UD), isolated in our previous study. The isolates were then subjected to ex vivo assays using primary rat hepatocytes incubated under humidified 5 % CO2 incubator at 37 oC. It was found out that urticol at 100?M stimulated glucose uptake by 28.57 % and 11.45 % as compared to the untreated control and pioglitazone at 100 ?M respectively (p=0.05) while the terpenoids were found to be non-bioactive at both 50 ?M and 100 ?M. This showed that urticol is stronger than pioglitazone in stimulation of glucose uptake. Therefore, the findings show urticol as a potent antihyperglycemic agent. This work may provide a scientific proof of the folklore antidiabetic activity of UD. Further work needs to be done to fully understand the exact mechanism of action of urticol in inducing glucose uptake. It is hypothesized that urticol may work by inducing Glut-4 expression on hepatocytes but this remains to be determined.

QoS Aware Resource Scheduling in Internet of Things-Cloud Environment[ ]


Internet of things (IoT) is a novel idea of linking objects. Establishment and functioning of IoT rely on existing networks as well new network infrastructures. Cloud environmentis an critical factor for the establishment and functioning of an IoT system. When cloud infrastructure is used for the establishment of IoT, it has to deal with heterogeneous workloads. These workloads include diverse applications with various priorities, performance and resource demands. There are tasks that are limited to the kind of machine types they demand for execution. Also, majority of the IoT applications are time bound and therefore task response time is an important QoS factor. Sub-optimal resource scheduling and sub-optimal load balancing will cause performance degradation. In this paper, we have proposed the concept of a QoS aware resource scheduling technique called Load Balanced Particle Swarm Optimization scheduling, which can reduce application response time and ensures load balancing.

Software Engineering[ ]


Software engineering is quite hard to define the meaning of what exactly software engineering is. It uses both engineering and science as a way to try to produce improvements with software technology. Different persons have somewhat different definitions of the term software engineering dependent upon what area they work in (Jonny, 2010).The history of software engineering will assist us to comprehend the issues that started for being obvious within the late 1960s and early seventies, as well as the solutions which may have led on the creation with the field of software engineering (Edeh, 2007). Software engineering is usually discipline when designing and implementing high performance data projects. Also software package engineers are certainly not certified or sanctioned by any standards body, by using software fitters with experience in the Intelligence community increases likelihood of success (John, 2009).

Data Warehousing Concepts Using ETL Process for Social Media Data Extraction[ ]


The importance of using social media has increased enormously and focus of the software analyst has shifted towards analyzing the data available in these social media sites. For Example if a college wants to retrieve the alumni data from the social networking sites. Yes it can be done by using power tool called ETL Tool that is available for analyzing the data. In order to analyse the data it’s important to have cleaned or preprocessed data. This preprocessed data helps us in retrieving the desired data. In this process, we need to create special type of database that is specifically built for the purpose of getting information out rather than putting data in. Data warehousing concepts using ETL process trying to build the Data warehouse. Not only alumni data can get the list of friends along with their bio-data, list of employees who are working in different industries. The data Warehouse exists to provide answers to strategic questions and assist managers of the organizations in planning for future. The beauty of creating Data Warehouse will enable the user to analyse the data. We use powerful Tool called Informatica to create this warehouse from social media.
