Temperature control becomes increasingly necessary with each day, be it in industrial, commercial or residential environments. In a similar way, technology has become a common tool in everyday life. Thus, the technologies need to accompany advances in the controls of processes in many fields, creating applications that can be used in mobile devices alongside these processes. Therefore, this paper proposes temperature monitoring of an environment, via Bluetooth wireless communication and with interface display on a mobile application, developed in MIT App Inventor. While implementing commands via hardware and software a procedure to lower room temperature was applied through a ventilation system. The data are collected through a DHT11 temperature sensor, and the wireless communication is through a HC-05 Bluetooth module, both connected to the development board Arduino. It was possible to condition the cooler to work accordingly with a preset temperature range by using its IDE (Integrated Development Environment). Thereby, this project is a low-cost and advantageous alternative to temperature control and monitoring supported by technological advancements.

An assessment of fragility of objects built (constructed) in urban environment to deliberately imposed abnormal actions (loads) is considered. The actions under analysis are explosions, vehicular impacts and fires that can be imposed by acts of terrorism and sabotage as well as such highly random events as car crashes into structures due to unintentional roadway departures. The fragility is assessed by means of mathematical models known as fragility functions and developed for vulnerable building and transportation structures, protective barriers, and energy supply facilities. The result of fragility assessment is the probability of the damage that can be foreseen and modelled by means of mathematical models used for structural analysis. The case is studied where information on an abnormal action can be expressed in the form of a small-size statistical sample with components acquired in post-mortem investigations of attacks or unintentional accidents. The basic idea is an application of the statistical (bootstrap) resampling for the estimation the damage probability. The resampling procedure is applied to values of the fragility function that can be developed for the damage caused by the abnormal action in question. The values of the fragility function are estimated for components of the small-size sample of abnormal action values. The resampling of the fragility function values yields a conservative estimate of the damage probability expressed by the limit of a one-sided confidence interval. The estimate of the damage probability can be applied to making decisions concerning the level of resilience of vulnerable urban objects.

This study focuses on identifying the weakest points of project management and the possibility of where artificial intelligence can help precisely in their optimization. The results were taken from a survey where project managers of various categories were asked about the main challenges facing management today and the points where artificial intelligence can be seen as a optimization tool. In this decade, artificial intelligence (AI) has undoubtedly been one of the most influential technologies. AI has changed the way people live and work, and project management is no exception. There is always controversy about the use of AI technology. In this paper first is explained the need for companies to use AI technology and after considering the advantages and risks of AI. Also using project management based on machine learning is the optimal option. Some proposals for the implementation of AI in project management are presented. The study describes how AI systems can support project managers to become more efficient in their work.

Fisheries, as part of the human food chain, have an environment that affects fisheries resources. The view of slowing the number of fish catches in the sea due to factors that drive such as economic growth, population and effort effectiveness will decrease the power of fish in the sea. This study carried out the circumstance of fisheries in sea Indonesia and analyzed empirically the relationship between economic factors, population, and effort effectiveness on the catch volume. We apply the random effect (RE) estimator method which is reviewed for 33 provinces for the period 2000-2015. We use catch as a proxy for marine ecosystems. Our results confirmed that the growth of fish catchment in the sea Indonesia experienced a positive trend and the relationship between economic factors, population and effort effectiveness positive and significant on the volume of catch thus we conclude that catch fisheries in Indonesia is sustainable

Project construction has never been a simple act, because it is conditioned by specific constraints of cost, time, quality, and it includes a degree of uncertainty. So, time is a vital aspect by which project success is judged; for this purpose, deadline compliance is a paramount question in project construction. In Algeria, delay has invaded the majority of projects. Therefore, it is necessary to give more importance to time management to reach the stage of projects success. As saying goes, “you can’t manage what you do not measure”; the quantification or the prediction of delays appears necessary to arrive at a good mastery and a better management of time. The objective of this paper is to quantify the probability of delays in construction projects. For this reason, data from 30 public projects has been collected, and then categorized into 4 groups according to their types: school groups, college, high school, administrative buildings and economic infrastructures. Subsequently, the simple linear regression method is used to develop prediction model for the public projects in Algeria; to enable managers and practitioners to predict possible delays. This prediction is intrinsic to minimize the risks, to widen the field of reflection and especially to increase the chances of project success.

This paper focuses on the integration of refugees and immigrants into Greek society through the provision of housing. This topic is a hot one due to the fact that many refuges have arrived in Greece during the previous years and there is a need to remain for a long time. Thus, the provision of housing is imperative. However, due to the economic crisis, the creation of such spaces is expensive and unachievable. As a result, alternatives should be examined. For this purpose, different policies of the smooth integration of refugees and immigrants in European countries can provide such solutions. Three case studies were selected across Europe and they have been compared to the Athenian paradigm. Through this research, proposals about their successful integration have been derived. In that way, it will be possible to provide specific plans that reorganize various areas in Athens in order to make this vision a reality.

Solar still is the ancient low cost device to distillate the saline water. Paraffin is a kind of phase change material which has a thermal storage characteristic and it can absorb and release a large amount of latent heat during the phase transition process. Ethylene Glycol was used as a PCM to study the thermal characteristics of water and absorption rate. A Nano phase change material plays a vital role in solar energy conversion and is used to enhance the thermal conductivity behavior on thermal energy storage systems. Materials at the nanoscale have a larger surface area and it has higher thermal properties than the macro particles. Incorporating NPCM into basin material helps to improve the productivity and the evaporation rate. The performance of the single basin double slope solar still was higher than the single slope solar still. Despite significant efforts, there are some challenges, such as the thermo physical properties of basin material, flow rate, insulation material and thickness that must be overcome in order for this technique to be useful in practice. In this paper, a detailed comparison of the various solar stills, designs, fabrications and water production analyses are discussed. Hence it is confirmed that NPCM has a higher potential than PCM for saline water desalination processes. This study confirmed that the Paraffin composites are stable up to 160°C and it increases the efficiency due to increased thermal properties of NPCM.
