Abstract:

This article reviews that lasers are being investigated as a way to uncover tiny imperfections in crucial ceramic components of diesel engines. Heavy-duty truck engines are designed to operate for a million miles or more. In their search for components that resist corrosion and wear, manufacturers have developed engine parts from ceramics, which have found their way into a number of commercial engine applications over the last 10 years. Under some conditions, the materials hold up better than steel, but they are not immune to weaknesses of their own. The machining of ceramic parts, for example

Abstract:

This paper presents a selected aspect of design activity devoted to optimising HALE and MALE UAVs. The project is taking place at Warsaw University of Technology under the V Framework of European Union in the CAPECON project. This paper deals with wing airfoil selection, defining of the configuration layout and power unit integration. A brief overview of wing sections developed in some design centres (mainly in Israel Aircraft Industry and in Northrop Grumman) is included. Aircraft layout depends on the mission and sensor selection and is discussed using the examples of PW‐103 and PW‐114. Engi

Abstract:

Utilizing the wind power in high altitude to generate electrical power has significant meaningful while the pollution of environment of the planet is becoming worse and worse. Wireless aerial surveillance platform is very important to military surveillance, while present method costs too much. To meet the requirements mentioned above, a long-endurance multi-function floating platform is proposed in this paper. The long-endurance multi-function floating platform mainly consisted of four parts: the floating platform, the ground control base, the control box and the controller. Fuzzy-PID is used

ABSTRACTTo improve the endurance performance of long-endurance Unmanned Aerial Vehicles (UAVs), a smart morphing method to adjust the UAV and flight mode continuously during flight is proposed. Using this method as a starting point, a smart morphing long-endurance UAV design is conducted and the resulting improvement in the endurance performance studied. Firstly, the initial overall design of the smart morphing long-endurance UAV is carried out, then the morphing form is designed and various control parameters are selected.

Abstract:

The impact of adding heavy-resistance training to increase leg-muscle strength was studied in eight cycling- and running-trained subjects who were already at a steady-state level of performance. Strength training was performed 3 days/wk for 10 wk, whereas endurance training remained constant during this phase. After 10 wk, leg strength was increased by an average of 30%, but thigh girth and biopsied vastus lateralis muscle fiber areas (fast and slow twitch) and citrate synthase activities were unchanged. Maximal O2 uptake (VO2max) was also unchanged by heavy-resistance training during cycling

Abstract:

Habitual ultra-endurance exercise seems to promote telomere length maintenance, especially at older ages. In addition, the beneficial effect of ultra-endurance training on biological aging is higher in ultra-trail runners who have been engaged to ultra-endurance training during many years. Finally, and for the first time, this study shows that the SOD2 rs4880 polymorphism has a significant impact on telomere length, as well as on acute inflammatory response to a 107-km trail race.

In other cases, endurance is the ability of the body to perform any physical activity for a long time without reducing its effectiveness, in other words, endurance is opposed to the process of fatigue.

Maximal strength was measured by recording how much pressure an individual could exert on an air-filled bulb.

Urinary samples were collected at the day before the race, during the whole RAAM, and, without a physical strain, seven days after the race.

Over the last 10 years, the use of micro air vehicles has rapidly covered a broad range of civilian and military applications.
