In a lexical decision task (LDT) in which list composition is manipulated, a typical finding to date has been a slowdown for easy items (e.g., high-frequency words) but little speedup for hard items (e.g., low-frequency words) when they are mixed together. This asymmetric frequency-blocking effect contrasts with the symmetric pattern (both a speedup for hard items and a slowdown for easy items ...

We consider the existence of blocking semiovals in finite projective planes which have intersection sizes 1,m+ 1 or n+ 1 with the lines of the plane for 1 ≤ m < n. For those prime powers q ≤ 1024, in almost all cases, we are able to show that, apart from a trivial example, no such blocking semioval exists in a projective plane of order q. We are also able to prove, for general q, that if q2 + q...

In this paper, a method for calculating blocking experienced by dynamic multicast connections in a single link is presented. A service center at the root of a tree-type network provides a number of channels distributed to the users by multicast trees which evolve dynamically as users join and leave the channels. We reduce this problem to a generalized Engset system with nonidentical users and g...

In this paper we propose a blocking-aware partitioning algorithm which allocates a task set on a multiprocessor (multi-core) platform in a way that the overall amount of blocking times of tasks are decreased. The algorithm reduces the total utilization which, in turn, has the potential to decrease the total number of required processors (cores). In this paper we evaluate our algorithm and compa...

Call admission control (CAC) plays a significant role in providing the desired quality of service in wireless networks. Many CAC schemes have been proposed. Analytical results for some performance metrics such as call blocking probabilities are obtained under some specific assumptions. It is observed, however, that due to the mobility, some assumptions may not be valid, which is the case when t...

This note accompanies the DCA algorithm paper [1] by Daniels et. al. This paper presents two channel assignment algorithms, one based on an Integer Programming (IP) model and the other based on a heuristic. The number of channels required to satisfy linearly increasing demand function in the randomly distributed Typev cells are presented here for reuse distances greater than 2 and 3. The result...

1. Propranolol, a beta-adrenoceptor blocking drug with local anaesthetic and a direct myocardial depressant action, and MJ 1999, a beta-adrenoceptor blocking drug which has no local anaesthetic or intrinsic sympathomimetic action, were compared for beta-adrenoceptor blocking activity in man.2. Propranolol was 2.67 times more active than MJ 1999 in reducing by 50% the tachycardia produced by the...

The communication blocking protocols of stopping or repeating a service in non-exponential queueing networks with blocking are shown to be equivalent under a partial balance condition. Examples both with a reversible and nonreversible routing are given.

A blocking semioval S in a projective plane of order q is a set of points such that every line meets S in at least one point (the blocking property), and every point of S lies on a unique tangent line (the semioval property). The set of points on the sides of a triangle, excluding the vertices, is a blocking semioval in any projective plane of order q > 2, and has size 3q − 3. The size of a blo...

Sanding is a very important process in MDF production. In this study, abrasive belts (P60 and P120) were used to conduct sanding experiments, mass variation, surface morphology, roughness of the measured analyze failure utilized belts. It found that belt mainly increased process. The increase range P60 within scope 0~0.02 g, while for P120, change mostly fluctuates 0~0.01 g. (Sa Sku) presents d...
