In order to successfully implement several control laws, a uniform upper bound for the Jacobian of the gravity vector is necessary. However, not all joint configurations of robot manipulators insure the existence of such a bound. In this paper we fully characterize the class of robot manipulators for which the Jacobian of the gravity vector is uniformly bounded. The results in this paper can be...

1 . Introduction . Most consistent nonparametric density estimates have a built-in smoothing parameter . Numerous schemes have been proposed (see, e.g ., references found in Rudemo, 1982 ; or Devroye and Penrod, 1984) for selecting the smoothing parameter as a function of the data only (a process called automatization), and for introducing locally adaptable smoothing parameters . In this note, ...

vision of its delivery of management leader naturally tends to disappear upon the product to the customers, since focus continually shifts to the next test coverage to insure that defective product is not shipped will also be overlookedunderestimated by such managers. Design techniques in the layout that contribute to greater yield will not likely be on their radar screen as their focus will be...

This note is a response to a paper of Ho that was published in Information and Management Sciences, 20 (2009), 161–171. We find two reasonable criteria to insure the existence and uniqueness of the optimal solution. Based on the same numerical examples, if we directly compare our results with that by Ho, then the improvement is about 30%. Meanwhile, after revising the computation errors, then o...

It is shown that in SO(10) and SU (5) models having a U (1) R symmetry, the requirement of breaking the unified group to the Standard Model leads to flat directions in the scalar potential. These can lead to a " cosmological modulus problem ". This is relevant to grand unified models of inflation, where U (1) R symmetries are often used to insure the flatness of the inflaton potential. A way th...

Key Points  Functional orthodontic techniques have been used to correct dentofacial deformities such as parrot mouth in the young horse.  An understanding of the orthodontic principles of tooth movement and the effects of forces on bone growth will insure the best surgical outcome.  The combined approach with retention wires of the upper jaw combined with a fixed acrylic and aluminum incline...

The future is moving towards offering multiples services based on the same technology. Then, billions of sensors will be needed to satisfy diversity these services. Such considerable amount connected devices must insure efficient data transmission for diverse applications. Wireless sensor network (WSN) represents most preferred technology majority Researches in medium access control (MAC) mecha...

We examine disaster reinsurance from the perspective of international risk-sharing. find that losses disasters are shared internationally to a generally very limited extent, unlike what theory risk-sharing suggests. propose new dataset cross-border payments for 93 44 economies in 1982–2017. Combining these balance data with industry data, we lack through results low participation primary insura...

We consider the problem of boundary control of an elastic system with coupling to a potential equation. The potential equation represents the linearized motions of an incompressible inviscid fluid in a cavity bounded in part by an elastic membrane. Sufficient control is placed on a portion of the elastic membrane to insure that the uncoupled membrane is exactly controllable. The main result is ...

Example Output • Type Strength – A language characteristic based on the amount of coercion (casting) permitted and performed among its data types  Less coercions = stronger typing – Coercion is generally performed during compile time to insure compatibility of operator and operand types – C integer coercions are rule based  Integer ranking  Integer promotion rules  Usual arithmetic conversi...
