Ten young male participants were recruited to test their maximum symmetric and asymmetric isoinertial lifting capabilities from floor to the knuckle height in different container dimensions varied in both width and length. The results showed that the order from the highest to lowest lifting capability for the lifting modes was symmetric lifting, asymmetric lifting with leg rotation and asymmetr...

A numerical trajectory optimization study of two types of lifting-entry reentry vehicle has been presented at low suborbital speed of 4.113 km/s and -15 degree entry angle. These orbital speeds are typical of medium range ballistic missile with ballistic range of approximately 2000 km at optimum burnout angle of approximately 41 degree for maximum ballistic range. A lifting reentry greatly enha...

In this paper, we investigate new lower bounds for the P=rj; qj=Cmax scheduling problem. A new bin packing based lower bound, as well as several new lifting procedures are derived for this strongly NP-hard problem. Extensive numerical experiments show that the proposed lower bounds consistently outperform the best existing ones.

Today, one of the most important research fields is concerned to the Engineering Design Process. It is focused on designing better electro-mechanical systems with a low impact on the environment and a most efficient use of the energy. Currently, the design process can take advantage of many computational-aided tools, which play a crucial role in the modern methods of optimization and reduce the...

Let k be a global field, with Galois group Gk and Weil group Wk relative to a choice of separable closure ks/k. Let Γ be either Gk or Wk, and H a linear algebraic group over F = C or Qp with p 6= char(k). Let ρ : Γ→ H(F ) be a (continuous) representation, always understood to be ramified at only finitely many places (as is automatic for commutative H, but not for H = GL2 with k = Q and F = Qp, ...

original article   health, safety and environment management has a vast area in which ergonomics aspects is known as one of the related aspects. in this case study the occupational hygiene by ergonomic intervention was focused. one of the prevalence activities among industrial sectors' worker in the developing countries is manual lifting tasks and other related physical activities which are imp...

We address the problem of minimizing makespan on identical parallel machines. We propose new lower bounding strategies and heuristics for this fundamental scheduling problem. The lower bounds are based on the so-called lifting procedure. In addition, two optimization-based heuristics are proposed. These heuristics require iteratively solving a subset-sum problem. We present the results of compu...

Granular Pile Anchor (GPA) considers one of the solution foundation techniques, designed to mitigate the lifting of the sole resulting from expansive soils. This study work is to investigate the uplift movement response of (GPA) in expansive soil. The laboratory tests have been performed on an experimental. The effects of several parameters, such as length (L) of (GPA) and diameter (D), the thi...
