Abstract :

The visible universe—including Earth, the sun, other stars, and galaxies—is made of protons, neutrons, and electrons bundled together into atoms. Perhaps one of the most surprising discoveries of the 20th century was that this ordinary, or baryonic, matter makes up less than 5 percent of the mass of the universe. The rest of the universe appears to be made of a mysterious, invisible substance called dark matter (25 percent) and a force that repels gravity known as dark energy (70 percent).Cosmological observations provide compelling evidence that about 95 percent of the content of the universe reside in two unknown forms of energy, which we call dark matter and dark energy-the first resides in bound objects in the form of non-luminous matter, the later in the form of  a zero point energy that pervades the whole universe. In this article I shall try to explore the essentials of dark matter and dark energy, with particular emphasis on the experimental evidence.

Abstract :

The innovation in cloud computing has encouraged the data owners to outsource their data managing system from local sites to profitable public cloud to increase affordability of services. But people can like full benefit of cloud computing, if we are able to report very real secrecy and security concerns that come with loading sensitive personal information then we have to increase security, privacy. In view of the huge number of data users, documents in the cloud, it is important for the search facility to agree multi keywords query and arrange for result comparison ranking to meet the actual need of data recovery search and not regularly distinguish the search results. Related mechanisms on searchable encryption emphasis on single keyword search or Boolean keyword search, and often sort the search outcomes. In our system, we explain and solve the interesting problem of privacy preserving multi keywords ranked search over encrypted cloud data, and create a set of strict privacy necessities for such a safe cloud data application system to be effected in real. We can add Document owner accounts, Cloud Server account, Admin account and grant permission to various privileges to different user.

Abstract :

The roof is a major component in building and housing construction and also it is the identity of the building or house. This study is focused on kingpost and beam joinery in gable roof types that commonly used in hotel entrances, cabanas, summerhouses, greenhouses and assembly halls in temples. For this study, the simplest structure of king post which is the structure that only the kingpost connects to the horizontal beam is used and mortise and tenon joinery is used to connect beam and king posts; the kingpost is used as a mortise element and beam is used as a tenon element. Therefore the ridge beam is a fixed which is supported at both free ends and is restrained against rotation and vertical movement. The study is considered the jack wood beam which has the length 198 inches (16.5 feet= 5.03m), 11 jack wood rafters that have the length 144 inches (12 feet) and two jack wood kingpost trusses that have kingposts with the length 44 inches (3.8 feet). Generally, carpenters in Sri Lanka use 8-11 feet as the range of standard distance between king post trusses. In this study, an attempt will be made to investigate the deformation of a ridge beam of under pressure exerted by rafters, tiles and kingpost trusses and from that to detect the optimum distance between kingpost trusses that can be used to design the king post beam joinery more effective way. Euler-Bernoulli Beam theory and Fourier series were the mathematical tools, which was used in the study. The shape of a deflected beam can be described by the Euler-Bernoulli Differential Equation. The results showed that the minimum deflection values have occurred at the standard range that used by carpenters. By examined those results, the optimum range for distance between kingpost trusses is 8-11 feet and when considering this range minimum deflection values have occurred around 9 - 9.5 feet. The results obtained from this study can be used to design the king post beam joinery more effective way.

Abstract :

The basic requirements for feed drives of turning machines with digital program control are formulated in this paper. The offered methodology for selection of such drives takes into account the specific features of the technological process, the processed material, the tools used, as well as the mechanical gear type. Concrete examples with DC and AC motor drives are presented, illustrating the practical application of this methodology. A number of models for computer simulation of two-coordinate electric drive systems have been developed, allowing study at various reference speeds, positions, and loads applied to the motor shafts. Detailed testing has been carried out by means of computer simulation and experimental research. The results obtained can be used in the design and tuning of such types of two-coordinate drive systems with position control.

Abstract :

Effects of Diesel on Fresh water fish (Clarias gariepinus) was carried out in the Fish Pathology Laboratory of the Department of Fisheries and Aquaculture, University of Calabar, Nigeria. About 200 fish were purchased from the University Fish farm, acclimated for 48h in the laboratory. The diesel used in this experiment was obtained from the University of Calabar power generating unit. Experiment was conducted in plastic containers of 10l capacity, each containing 10 fish and 5l of diesel in different concentrations (0.25, 0.37, 0.50 and 0.75g/l). The control tanks had similar number of fish and same volume of water without diesel. The tests and control tanks were replicated three times under same laboratory conditions. The duration of the experiment was 96h with hourly observations for abnormal fish behavior and mortality. Erratic swimming behavior, fast opercula movement and hanging on the water column and weakness were observed in test tanks only whereas fish in the control were calm and normal. Mortality of fish (3, 5, 7 and10) occurred in the test concentrations respectively within the duration of the experiment. Histopathology of gills of affected fish showed damaged gill lamellae, similar changes were not observed in the histological sections of the control fish. Mortality data obtained were analyzed graphically by plotting % fish mortality against log concentrations of diesel. The concentration of diesel in which 50% fish mortality (LC50) occurred was 0.37g/l. The results of the experiment led to the conclusion that diesel at different concentrations has deleterious effects on fresh water fish (C. gariepinus) and could cause mortality on repeated exposure to the organisms at higher concentrations. Fresh or used diesel should not be discarded into the environment to safeguard freshwater fish and other organisms. Further study on the effects of diesel on the food chain is recommended.

Abstract :

This Nowadays, research in computational agents capable of rational behaviour has grown widely. The formalizations of agents and their implementations have proceeded in parallel in different areas. In the games theory the behaviour of agents is relevant and necessary. We presented a novel approach about a computational agent that plays efficiently the well-known game connects four. This agent includes a reasoning module for decision-making based on A-Prolog (Answer Set Programming). Our aims in this article are firstly to briefly summarize the key concepts of decision theory and game theory. Next, we present a novel implementation about an agent in the game connect four that shows a perfect union between two different paradigms that have shown efficiency (A-Prolog & Java). This article shows the effective use of A-Prolog as a modeling language. We show that our A-Prolog-based approach can naturally satisfy the above requirements, through an A-Prolog encoding of the connects four game.
