There are two main different ways for benefiting from solar energy. The first and the most common way is through a photovoltaic (PV) solar system that converts solar radiation into electricity. The other way is through solar thermal conversion. For sun-enriched regions, the solar thermal solution might be a very practical one at the residential level. In both ways, their use leads to reduce the consumption of fossil fuels for energy generation and thus it reduces the proportion of harmful gases such as Carbon dioxide (CO2) emissions. The comparison is carried out focusing on solar thermal collector and PV systems. Results have shown the superiority of the solar thermal collector over PV based system in hot climates while in cold one both efficiencies become comparable to each other.

Such turbines are needed in regions with dense population such as Gaza Strip where the majority of the population are living in urban areas and they seek to reach energy self-sufficient buildings due to the severe electricity shortage in the local grid. The main consideration for a VAWT wind turbine to be suitable for urban areas is the safety factor. Another consideration is being able to turn and produce electricity at low wind speeds. Those two factors will shape the design of the VAWT wind turbine. The designed wind turbine should be compact enough to be installed on rooftops. A target power rating of 5 k Watt is set for the wind turbine as a considerable amount of power to supply a typical residential home. The efficiency of the designed wind turbine is validated experimentally by the recorded wind speeds from an anemometer and the estimated harvested power from the turbine itself. Further schemes and modifications on the design are suggested for improving the power efficiency.

Therefore, they experience a huge financial loss due to inability to properly automate the monitoring and control of environmental factors such as temperature, humidity, light and air quality and to ensure an adequate supply of feed and water. These factors adversely affect the chicks and leaving them uncontrolled might cause health problems for the chicks. This affects the chicks' feed intake and leads to an increase in mortality rate and increases chances of diseases. Therefore, this paper seeks to address automating those factors by developing an embedded poultry farm. The system consists of a PLC or a microcontroller, actuators, and sensors as major components. We display data collected from the sensors to the operators of the farm. The system is able to sense environmental parameter status and responds accordingly to regulate and maintain an optimum condition for improved health conditions for the chicks. The automated system improves productivity and environmental or climatic conditions in the poultry farm, making it conducive for the broiler chicks.

Because of the increasing number of accidents resulting from passing over bumps at high speeds, there is a need for a mobile application that detects those bumps and warns drivers before reaching them. We propose a mobile application that uses smartphones sensors to tackle this problem. The app works on reading data captured by smartphone sensors and analyzing them. Using a smartphone, we do not need vehicle-mounted sensors. GPS and accelerometer sensors are the main sensors used to capture data. Using those sensors, we obtain data of position, speed, and acceleration, which are needed for detecting bumps and their location and later the marked bump location, is used for warning drivers. In contrast to most applications in this field, this work uses internal sensors of smartphone, resulting in an inexpensive system available at the hands of every user. Experimental results show basic functionality of the system.

D... more Freshwater shortage is a major problem and a challenge facing the population in the Gaza Strip. Due to the increasing population, there is a growing demand for freshwater for human consumption and agricultural purposes. Rainwater is the only renewable resource and it feeds Gaza’s coastal aquifer which is the primary water source in the strip. Such a challenge motivates us to conduct research on measuring falling rainwater which substitutes for the drain in the aquifer of the Gaza Strip. This work aims to develop an automated system that measures rain amount with sensor network at different sites in the Gaza Strip and to build an accurate rain map that can be used in different applications e.g., to find out the best places to harvest rainwater and to provide farmers with rain data so they improve their agricultural production. Arduino platform is used for developing the proposed system. The Arduino is equipped by Global System for Mobile (GSM) module to transfer rain data wirelessly with high accuracy. An Android application was developed for reading this data and sending it to the firebase. Other applications e.g., an iOS application displays this data based on the user’s location where the Gaza Strip was divided into several regions and each region has its own rain data.

The motivation for our research project is the increasing need for road status and traffic monitoring services as the demand for motorized transportation is growing while having limited resources of highways, parks and roads. We use smartphones as a platform for implementing our system because they come equipped with a wide range of sensors. The most important sensors for our project are the accelerometers and gyroscopes which constitute the inertial measurement unit (IMU) and the positioning devices based on a satellite constellation such as GPS, GLONASS and Galileo. Moreover, they have detailed maps of the roads for easier navigation. Other professional road monitoring sensors such as Antilock Brake System (ABS) sensor which already exists in modern vehicles can be interfaced in a modular fashion to our system. The uniqueness of Smart P2 Road is to integrate several sensors and devices with a strong emphasis on trust, privacy, security and dependability for reliable use by public users and local authorities. The integrity is verified through experimental monitoring of roads across Gaza Strip, Palestine and Amman, Jordan. In those experiments we collect various sensory data, keeping in mind respecting the privacy of the driver as a priority. These collected data were processed and classified using k-means algorithm. The preliminary results show a success rate of 95% for the underdevelopment system. Index Terms-Smart phones; inertial measurement unit (IMU); GPS; Roads' traffic and conditions monitoring; k-means algorithm.

Also, the question of renewable energies is rising for environmental reasons, because the renewable energy use no emissions of pollutants such as carbon dioxide, nitrogen oxide and sulfur dioxide as in the case of conventional electricity generation in power plants. This article examines the different renewable energy types and their definitions. Stepping into renewable energy is explained and illustrated. Here, the advantages and disadvantages of types of energy are considered and compared in order to determine the use of profitability. In addition, the distribution of individual types of energy taken in general considered.

Managing and protecting assets is an important issue and usually a dedicated person at the institute carries out this work in a bureaucratic way. In this work, we describe an innovative technological solution to the management problem of using traditional mechanical keys. Based on this need, the aim of this work is to design and implement an automated assets and keys management system. In the proposed system, one can keep the keys in a key-cabinet, which can be locked or opened automatically. We rely on near field communication (NFC) technology, which exists in most of the modern smart phones, to identify each key. Our main controller will be an Android based smart phone interfaced through its headphone jack to control the key-cabinet lock. The smart phone contains all needed hardware and software components to achieve our goal. The employees can borrow the keys easily using their NFC identification tags without using paper records. The opening of the key-cabinet door is controlled using a dedicated smart phone mounted near the key-cabinet. Moreover, employees will be able to borrow and return keys in any time and keep their track recorded in a mobile application.

TRNSYS program is used to predict solar useful energy gained by the collector. The Design-Expert (DOE) tool with response surface methodology (RSM) program is used to optimize the tilt angle. Results show that tilt angle and the incidence angle have important effect on the gain of the useful energy. In addition, it is shown that the optimum tilt angle varies monthly or seasonally. Moreover, to get maximum useful energy, the incidence angle has small angle around 10° and almost stable throughout the seasons. The optimal tilt angle has lowest value in summer and the highest value in winter. The calculated values are of 39.57°, 26.72°, 20.15°, and 32.2° and the corresponding maximum monthly averaged useful energy gained by the collector in January, April, July, and October are 223.52 kWh, 482.61 kWh, 596.56 kWh, 386.51 kWh respectively.

Modern navigation systems are based mainly on satellite and inertial sensors. Inertial sensor systems are becoming very popular in navigation systems because they are self contained sensors. The goal of this research is to develop novel approaches for improving the performance of inertial sensor systems and their integration algorithms with external sensors such as global positioning system (GPS) and magnetometers. The standalone inertial navigation system (INS) is dependent on the inertial measurement unit (IMU). An IMU is traditionally composed of three orthogonal gyroscopes and three orthogonal accelerometers. In the inertial sensors side, we focus on the use of distributed accelerometers for inferring the angular motion from the angular information contained in their measurements. There exists a variety of reasons for conducting th...

Unlike the rate gyroscope in an IMU, the camera based visual-gyro does not suffer from drift errors. In order to overcome the drawbacks of the standalone systems, an INS/visual-gyro integration using direction cosine matrix (DCM) models is presented. Compared to the conventional Euler angle models, the usage of DCM can provide linear system models and avoided singularity problems. Using iterative closest point (ICP) algorithm, the depth measurement from a RGB-D camera can be converted to positioning information and further added to the integrated navigation system. To show the performance of the presented system, one field experiment is carried out with a mobile robot and the numerical results are shown.

A two-layer hierarchical architecture has been implemented and tested in realistic environments. The lower-level controller accepts velocity commands from the higher-level and takes care of the nonlinear dynamics of the vehicle. The higher-level controller, on the other hand, integrates motion coordination and Kalman filter based localization techniques. The result is a cost effective mobile, flexible robot platform ideal for research in cooperative robotics and motion-enabled sensor nets. Experimental results validate the performance of the mobile robot and architecture described herein.

These days, there are numerous equipment or parts inside machines called heating elements particularly with electrical or electronic devices and they should be cooled during the working process. However, with respect to their size, manufacturers are minifying day by day to satisfy requirements of users but the power should be maintained. Hence, elements withstand a high amount of heat and high heat flux (transition/mutability) is being generated during the working process. The main contribution of this study is to investigate thermal solutions using four cooling tools and to compare to each other and consider thermal design guidelines and factors as well. Furthermore, we review the appropriate thermal solutions for the produced heat from the electronic equipment and we present the effective and suitable tools which use...
