Recently several interesting patch antenna structure was proposed. In this paper, we propose a new rectangular structure in the symbol of dollar, the proposed antenna, fed by a microstrip line, is made with FR4 substrate, and a thickness of 1.6mm, and relative permittivity 4.4. The ground plane on with the antenna is printed contain two slots. The resulting antenna has been found to possess a compact size of 30 mm × 30 mm, which is suitable for wireless local area network (WLAN). Two resonant frequencies are obtained for the proposed antenna; the low-band resonant frequency is located at about 2.4GHz, with -10 dB impedance bandwidth from about 1.9 GHz to 3 GHz, and the higth-band resonant frequency is located at about 8.8 GHz, with -10 dB impedance bandwidth from about 7.6 GHz to 10 GHz. \nIn the first stage, we’ll propose a comparison study of a patch antenna with slots and without slots, and in the second part we’ll present the study of antenna parameters effect dimensions.

As per the recent statistical data, the consumption of fuel has increased since 1965 to 2012 at very high rate. Earlier, we used to relay mostly on coal for running steam engines and with the advancement of technology, this switched over to gasoline, diesel, natural gas and alternative fuels. The majority of emission coming from automotive engines was considered to be the main contributor of air pollution. Aqua silencer was introduced to avoid release of such gases directly into atmosphere from diesel engines. It was fitted to the exhaust pipe of the diesel engine to treat the toxic gasses before releasing to the atmosphere. It not only reduced the regulated emission but also it reduced particulate matter significantly. The particulate matter was reduced by the use of activated charcoal layer. It is highly porous and possesses extra free valences so, it has high absorption capacity. Thus, adsorbs the gases from the engine and releases much less pollution to the environment. Sound produced under water is less hearable than the sound produced in atmosphere. This is because of the small sprockets in water molecules, which lowers its amplitude thus, lowers the noise level. The noise and particulate level were found to be less by 40 and 93 percent respectively when compared with the conventional silencer and it’s easy to install. This system can be safely used for diesel driven units which could be used in inflammable atmospheres, such as refineries, chemicals processing industries, open cost mines and other confined areas, which demands the need for diesel powered engines.

This paper studies the applying of the controller in the suspension system of car. In order to deal with disturbances and uncertainties, the sliding mode control method has been used as a resistant method as well as a controlling method applied on system. This controller with a Quarter model of car uses the mathematical linear combination of an ideal model Sky-hook and an ideal model Ground-hook as a reference model that this reference model causes to simultaneously have both factors of the comfort of car passengers and more proper conductibility. Stimulation of the suspension system of car causes the effect of applied controller on the dynamics of car’s cabin and dynamics of its wheel. In this paper, both stable and transient states have been used as the stimulation entering to the system and the effects of both states on dynamics of car’s cabin and its wheel have been investigated. The obtained results show that there are states in which there is the equilibrium between the appropriate response of car’s cabin and its wheel. This balance causes the shift in emphasis of reference model on the controllers of sky-hook and Ground-hook through changing the advantage of dual controller.

Light is considered as one of the most important spatial constituent elements. In addition to its dynamic and lightness in architecture space, it’s intrinsic and spiritual senses can be noted in worship space. The role of light in space is so that it conducts audience to the desired place with a variety of spectrums and comes with the experience of time. In this study, the view of contemporary experts of architecture as well as the philosophy of illumination can be important, because they give importance to the element of light. So, in this study the concept of light is divided into three categories: spiritual, psychological and physical importance that this study in the view of spirituality addresses the importance of light in all religions and its result is canonization of the element of light. In the presented categorization of light, the light can be referred as warm light, cold light, visible light and invisible light. The elements affecting the formation of light can be divided into the controlling elements and absorbing elements. The method used in this research is a combination of text analysis method, exploration method and interpretation method. Therefore, texts, documents and evidence related to the topics of this study were studied, compared and analyzed and according to them, the present paper is composed of two parts: first, it addresses the definitions from different points of view and the role of light in the architecture of mosques and then it examines the elements affecting the formation of light in designing the space of mosques.

Carefully scheduling the operations of pumps can be resulted to significant energy savings. Schedules can be defined either implicitly, in terms of other elements of the network such as tank levels, or explicitly by specifying the time during which each pump is on/off. In this study, two new explicit representations based on time-controlled triggers were analysed, where the maximum number of pump switches was established beforehand, and the schedule may contain fewer switches than the maximum. The optimal operation of pumping stations was determined using a Jumping Particle Swarm Optimization (JPSO) algorithm to achieve the minimum energy cost... The model integrates JPSO optimizer and EPANET hydraulic network solver. The optimal pump operation schedule of VanZyl water distribution system located in was determined using the proposed model and compared with those from Genetic and Ant Colony algorithms. The results indicate that the proposed model utilizing the JPSP algorithm outperformed the others and is a versatile management model for the operation of real-world water distribution system.

This work presents the dynamic graph cut based Otsu’s method to segment the masses in mammogram images. Major concern that threatens human life is cancer. Breast cancer is the most common type of disease among women in India and abroad. Breast cancer increases the mortality rate in India especially in women since it is considered to be the second largest form of disease which leads to death. Mammography is the best method for diagnosing early stage of cancer. The Computer Aided Diagnosis lacks accuracy and it is time consuming. The main approach which makes the detection of cancerous masses accurate is segmentation process. This paper is a presentation of the dynamic Graph Cut based approach for effective segmentation of Region of Interest (ROI).

Heterogeneous Networks (HetNets) are collected number of multi-mode, multi-layer, and multi-band network structures and utilize cells of varying sizes. Femtocells (HeNodeBs) are implemented to extend and strengthen the coverage in indoor. However, these random HeNodeB deployments raises co-tier and Cross-tier Interference (CS-TI) which results system performance degradation. This paper proposes the self-organized Joint Sensing and Power Allocation scheme (SJSPAS) in the uplink to minimize the for LTE/LTE-A HetNets. The proposed scheme is a joint sensing and power control approach. Moreover, a sensing algorithm proposed which is inherited from Fireflies algorithm. The novel proposed scheme is simulated by Monte Carlo simulation which demonstrates that the scheme efficiently improve the uplink throughput of the macro-eNodeB and provides better HeNodeB throughput than the existing conventional power control techniques.

Some reproduction aspects of the \"doctor fish\", Cyprinion macrostomum, were examined for the first time from the Tigris River drainage. A total of 316 specimens were caught from Gamasiab River in western Iran, at monthly intervals throughout the year. Age, sex ratio, fecundity, oocytes diameter, gonado somatic (GSI), modified gonado somatic (MGSI) and Dobriyal (DI) indices were estimated. Regression analyses were used to find relations between fecundity and fish size (length and weight), gonad weight, and age. Sex ratio differed significantly from unity, and the percentage of males was greater than that of females. The mature females and males were longer than 108 mm and 94 mm in total length (+2 and +1 in age, respectively). The GSI ranged between 0.09-2.94% and 1.70-15.53% for males and females, respectively. Gonad indices showed spawning took place from May to August, when the water temperature was 16 to 24 °C. The average diameter of the oocytes ranged from 0.2 mm to 1.7 mm, in the spawning season. The averages of absolute and relative fecundity (relative to body weight) were 3642.51 eggs (SD ±1219.92) and of 55.04 (SD ±14.12) per gram body weight, respectively. The absolute fecundity was significantly related to body weight and ovary weight.

One of the effects of the climatic changes phenomenon is the change in precipitation (rainfall) variables. In the present research, the statistical period of 41 years (1970-2010) in 20 stations at Karkheh Basin station is investigated. The aim is to detect the trend of climatic changes in annual precipitation variables , maximum precipitation, the number of annual precipitations in stations using parametric and non-parametric climatic models (Man Kendal test), Man Kendal ranking test , Sen. test (Q), Regression model (LR), Spearman correlation coefficient (SRC), Pre-whitening test, standard deviation analysis (Std) and t-student test. The results showed that there was significant trend of reduction in 0 of the stations, and that ` displayed no trend in the annual precipitation parameters. The climatic changes experienced significant increase in 5. 45% without trend, 20% decreases and maximum precipitation had 50% significant increases compared to annual precipitation. But, the significant increase or decrease in some precipitation variables was different using applied models. Generally, the efficiency of mentioned tests was not consistent in the change in the precipitation variables, which indicates the uncertainty in the outputs of different models.

Building industry hasn’t been developed increasingly in contrast with the other industries which as an old industry spend lots of national invests every year and also it needs to more care. Today’s, one of the main indices in determining the role and the position of the building industry in huge economical policies is the level of investment in different parts of it for every country. In our country, most part of residential investment is done without optimum management and just done by individual investors, benefit without any identification. Lack of scientific and technological competence causes no care for the buildings characteristics and strength, loss of materials, increase of the finished prices of the residential apartments and as a result loss of the national invest of the country. On the other hand, there is no way except use of industrial producing procedures of the building in order to minimize supply against demand. As a result of increasing the country young population and the finished price of the residential units.\n Unfortunately, lack of correct conduct of the industrialization methods in the country in spite of it’s advantages has been caused not only there was no decrease in time and cost of these structures but also, there was increase in time and cost in contrast to traditional structures and finally these structures don’t have the standard quality.\n In this article, it is tried to identify and study the conducting obstacles and difficulties of the industrial buildings in order to prepare the condition for producing a lot of industrial buildings in the country by offering the necessary strategies.
