Due to their efficient flight control systems and their camera of high quality modern drones can fly precisely and take aerial photos of high resolution. Although these multi-rotor devices are not able to fly long distances yet, they are very efficient instruments for taking aerial photographs of their proximate environment. As they are able to…

This article presents the design and realization of decoder mobile for distress beacon 406 MHz. The use of the sparse Fourier transforms in the processing of distress beacon signals. The characteristics of these decoders are mobility, able to decode all the frequencies of the beacons. It locates with great precision the location of the emitting…

Almost every cells in human’s body contain the same number of genes so what makes them different is which genes are expressed at any time. Measuring gene expression can be done by measuring the amount of mRNA molecules. However, it is a very expensive and time consuming task. Using computational methods can help biologists to…

With the introduction of new services and new more sophisticated mobile devices the radio network operators are faced with new challanges to increase the system performance. The most recent standards introduced by 3GPP for the new architectures of the Long Term Evolution network address these issues and outline possibilities for optimizing network performance and user…

The idea of monitoring several types of parameters in various environments has been motivating significant research works in Internet of Things (IoT). This paper presents the design and construction of iSensA, a system for integrating and collecting information from sensors. The solution implements a multi-sensor monitoring system and then expands the monitoring concept to an…

To gather information rapidly in disaster sites, a lot of search/rescue robots have been developed. It is difficult to correspond to the complicated environment composed of fields requiring various locomotion strategies, because most of these robots have only one type of locomotion device. To increase the available search routes under such conditions with the aim…

There is no doubt that the wind was the renewable source of energy that had the most significant growth during the last five years, and more importantly, the wind power source in Brazil has always been the cheapest and most competitive of all the others, so it is worth saying that wind have never been…

In this age of smart devices, many people are carrying a smartphone with them all the time. When they are at home, most of them are connected with the home Wi-Fi network. In this paper, a Wi-Fi network based architecture is proposed to control home appliances using a smartphone and also with a touchscreen-based wall…

This is a comparative study on the behavior of a dual medium height building with different walls solutions, in a high seismic area (Bucharest, Romania). The main feature of those buildings is the placement of load bearing walls on the perimeter of the building. This is done to limit the lateral displacement when the structure…

Proportional navigation (PN) is a widely-used guidance law for missiletarget engagement. The goal of the missile intercept problem is to reduce the closest distance between the missile and target by diminishing the line-of-sight rate (LOS rate). In general, PN guidance law necessitates information of the LOS rate and missile velocity. The closing velocity (relative approaching…

The paper shows the influence of nonbearing masonry walls for medium rise framed buildings placed at higher stories but not at the ground floor. The building studied here is a hotel that will be built in Bucharest, Romania. This is a high seismic area according to the seismic codes in force. The structure is composed…

Optical switching provided the means for the development of Data Centers with high throughput interconnection networks. A significant contribution to the advanced optical Data Centers designs is the Nephele architecture that employs optical data planes, optical Points of Delivery (PoD) switches and Top of Rack (ToR) switches equipped with 10 Gbps connections to the PoDs…

The drive for this report is to inaugurate the innumerable techniques espoused by the refactoring tools in coding development. The software product is a very complex and time-consuming process of development. Difficulty understanding and maintaining poorly designed software systems Software maintenance can take up to 50% of total development costs for software production. As a…

This paper showed visualization of technics about cardiopulmonary resuscitation contributed to acquiring the skills and understanding them. Especially, this system is focused on the individuality in each object (men, women, and babies) There are problems of a general cardiopulmonary resuscitation (CPR) training because learners are generally taught by instruction based on a subjective judgment. Because…

This was a study on the behavior of a confined masonry bearing wall in a medium height dual building. This wall had to be placed at one corner of the building. It had to be a masonry wall, not to be too stiff and drag the rigidity center too far from the building’s center. The…

This is a study on a confined masonry slender walls building in a high seismic area. The structure also contains frames, but the walls bear most of the gravity and seismic loads. The building will be used as a school. It will be built in Bucharest, Romania. It contains a ground floor and 2 stories…

This is a study on non-bearing masonry walls, in a high, reinforced concrete walls building. It will be built in Bucharest, Romania. This is a high seismic area. The building will be used as a dwelling. The structure is composed of a ground floor and 10 stories above. It is interesting to see the interaction…

Exploring the ocean underneath has always been an area of great scientific and environmental concern. However, the study of underwater environment was very difficult due to the extreme conditions. Undersea descriptions undergo severe distortion attributed to absorptive as well as scattering properties. Absorption substantially removes illumination, whereas a ray of light redirected in several path…

Power consumption is becoming more and more important in the Internet of Things (IOT). The ADC is the main power hungry in multi-sensor electronic systems and effectively reducing ADC power consumption without affecting ADC characteristics is an important. This paper is extended from the conference paper. The segmented SAR ADC presents reconfigurable 9 to 12-bit…

Climate change, increasing fuel oil prices and new international regulation on ship emissions lead to more focus on shipping fuel consumption and energy efficiency. There are various solutions for improving the ship energy efficiency. In this manuscript, we aim to present a real case of energy saving by adopting the central cooling system with box…

This study presented a prototype augmented reality (AR) application that helps visualize the affordances of everyday objects for infants in their home environments to prevent accidents and promote development. To detect and visualize affordances, we observed 16 infants regarding how they perceive and handle common objects from 4 to 12 months of age in their…

There are high expectations for commercial cloud services as an economical computation resource when executing scientific computing workflows, for which the computation is increasing on a daily basis. However, no method has been developed for determining whether a scientific computing workflow can be executed at a low usage cost, and thus scientists have difficulty in…

Our research deals with the single-vehicle routing problem (VRP) with multi-shift and fuzzy uncertainty. In such a problem, a company constantly uses one vehicle to serve demand over a scheduling period of different work shifts. Our issue relies on a routing problem in maintenance jobs, where a crew executes jobs in different sites. The crew…

Predicting the impact of suicide on incidental witnesses at an early stage helps to avert the possible side effect. When suicide is committed in public, incidental observers are left to grapple with it. In many cases, these incidental witnesses tend to experience the emotional side effect with time. In this study, we employed a Machine…

Identity and Access Management (IAM) and Single Sign on (SSO) are two security concepts that are related to each other. IAM governs the user access in an organization whereas SSO facilitates the user by authenticating to one centralized application and not having to re-authenticate when trying to access other applications. This paper addresses the different…
