A kinematic mapping of planar displacements is used to derive generalized constraint equations having the form of ruled quadric surfaces in the image space. The forward kinematic problem for all three legged, three degree of freedom planar parallel manipulators thus reduces to determining the points of intersection of three of these constraint surfaces, one corresponding to each leg. The invers...
The authors report the case of a 13-year-old patient with neurofibromatosis (NF-I), who suffered blunt trauma to the left tibia in 1993. The diagnosis of subperiosteal hematoma was made. Treatment consisted of temporary rest. There was a recurrence in 1996, and the subperiosteal hematoma was drained. In 1997, a shortening osteotomy of the left tibia was performed. However, massive gigantism wit...
BACKGROUND Venous leg ulceration is a common and costly problem that is expected to worsen as the population ages. Current treatment is compression therapy; however, up to 50 % of ulcers remain unhealed after 2 years, and ulcer recurrence is common. New treatments are needed to address those wounds that are more challenging to heal. Targeting the inflammatory processes present in venous ulcers ...
Falling is a common problem in the growing elderly population, and fall-risk assessment systems are needed for community-based fall prevention programs. In particular, the timed up and go test (TUG) is the clinical test most often used to evaluate elderly individual ambulatory ability in many clinical institutions or local communities. This study presents an improved leg tracking method using a...
Venous leg ulceration is a common problem in older people that adversely affects their quality of life. It is also a major cause of morbidity for many patients in hospital and community settings. Patients experience considerable pain and distress as a result of this condition and annual costs to the NHS are high. However, good nursing management and the correct use of compression therapy can le...
A local stability analysis is given for both the analytic and numerical solutions of the initial value problem for a system of ordinary differential equations. The standard linear stability analysis is reviewed, then it is shown that, using a proper choice of Liapunov function, a connected region of stable initial values of both the analytic solution and of the one-leg fc-step numerical solutio...
This paper addresses the question of embedded human motion sensing, in the framework of interaction with an artificial controller, either for activating a robot or for stimulating impaired human links. After a short presentation of the sensing problem and of the related measurement technologies, we describe the two main applications we have considered. The first one is the early detection of th...
In this paper we consider the problem of designing a container liner shipping feeder network. The designer has to choose which port to serve during many rotations that start and end at a central hub. Many operational characteristics are considered, such as variable leg-by-leg speeds and cargo transit times. Realistic instances are generated from the LinerLib benchmark suite. The problem is solv...
Splay Leg in a Dutch Laboratory Rabbit Colony: Detection Methods and Effective Elimination Procedure
In rabbits, especially in some races, limb movement disorder called splay legs, are mostly unilateral or bilateral in front or hind legs at an early age. The severity ranges from mild to severe in this case. In breeding colony of albino Dutch laboratory rabbits, the splay leg disorder has been observed over the years permanently.Within the scope of this research, 1.5-2.5% of 700-750 number of c...
A dual stator winding squirrel-cage induction motor (DSWIM) is a brushless single-frame induction motor that contains a stator with two isolated three-phase windings wound with dissimilar numbers of poles. Each stator winding is fed by an independent three-phase inverter. The appropriate efficiency of this motor is obtained when the ratio of two frequencies feeding the machine is equal to the r...
