Janssen TWJ. Effects of 16-week hybrid cycle versus handcycle exercise on fitness and physical activity in inactive people with long-term spinal cord injury. Spinal Cord. Abstract Study Design: Open randomized controlled trial. Objective: To investigate the effects of a 16-week hybrid cycle versus handcycle exercise program on fitness, pulmonary function and physical activity in inactive people...

In this paper we address the general multi-period production/inventory problem with non-stationary stochastic demand and supplier lead time under service-level constraints. A replenishment cycle policy (Rn,Sn) is modeled, where Rn is the n-th replenishment cycle length and Sn is the respective order-up-to-level. Initially we extend an existing formulation for this policy in a way to incorporate...

in this paper, a new combined power and refrigeration cycle is proposed, which combines the rankin power cycle and the ejector refrigeration cycle. this combined cycle produces both power output and refrigeration output simultaneously. this cycle is driven by the flue gas of gas turbines, industrial waste heats, solar energy and geothermal energy. an exergy analysis is performed to guide the th...

We analyzed serial dependencies in periods and asynchronies collected during oscillations performed in synchrony with a metronome. Results showed that asynchronies contain 1/f fluctuations, and the series of periods contain antipersistent dependence. The analysis of the phase portrait revealed a specific asymmetry induced by synchronization. We propose a hybrid limit cycle model including a cyc...

The life time of a component is defined by the reliability demands place on it due to its operating environment and operation conditions. To evaluate the necessarily thermal / power cycle stability of a power semiconductor module in a hybrid electrical vehicle (HEV), a vehicle driving cycle profile is used to calculate the thermal reliability requirements. The calculations are based on power lo...

This paper presents and investigates different approaches to solve a new biobjective routing problem called the ring star problem. It consists of locating a simple cycle through a subset of nodes of a graph while optimizing two kinds of cost. The first objective is the minimization of a ring cost that is related to the length of the cycle. The second one is the minimization of an assignment cos...

In this paper we consider an NP -hard hybrid flow shop problem with machine setups and cycletime minimization. The above issue is an important generalization of a flow-shop problem with minimization of a cycle time, and it stays in a direct relationship with a flexible job shop problem. In the hybrid problem task operations are performed by machines arranged in slots, i.e., a set of machines wi...

The effective treatment of malaria can be very complex: Plasmodium parasites develop in multiple stages within a complex life cycle between mosquitoes as vectors and vertebrates as hosts. For the full and effective elimination of parasites, an effective drug should be active against the earliest stages of the Plasmodium infection: liver stages (reduce the progress of the infection), blood stage...

This chapter presents further investigations into the period-three route to chaos exhibited in the passive dynamic walking of the compass-gait biped robot as it goes down an inclined surface. This discovered kind of route in the passive bipedal locomotion was found to coexist with the conventional period-one passive hybrid limit cycle. The further analysis on the period-three route chaos is rea...
