Regular forms of Amdahl’s law and the universal scalability model are functions of the number of processors p alone, therefore modelling only data sets with a single machine varying in its processor count. This paper demonstrates how these performance models can be expressed in terms of intrinsic machine characteristics such as: processor clock; external resource access speed; total threads; et...

Lightweight threads are becoming increasingly useful in supporting parallelism and asynchronous events in applications and language implementations. Traditionally, lightweight threads are supported only within the single address space of a process, or in shared memory environments with multiple processes. We introduce and describe the design of Chant, a runtime system supporting lightweight thr...

In the following, RA refers to [MR95]. 1. JL also preserves angles. Show that the Johnson-Lindenstrauss lemma also (1±ε)-preserves angles among triples of points of P (you might need to increase the target dimension however by a constant factor). [Hint: For every angle, construct a equilateral triangle that its edges are being preserved by the projection (add the vertices of those triangles [co...

In a commercial Relational Database Management System (RDBMS), sort and join are the most demanding operations and it is quite beneficial to improve the performance of external sort and external join algorithms that handle large input data sizes. This paper proposes parallel implementations of multi-threaded external sort and external hash join algorithms to accelerate IBM DB2, one of leading R...

Submit Manuscript | http://medcraveonline.com There are three main types of threads currently available; polydioxanone (PDO), polylactic acid (PLA) and polycaprolactone (PCA). PDO threads have been around the longest and are made of a synthetic biodegradable polymer that has been used in surgery for many years. PDO threads are absorbed into the body over 6 months by hydrolysis and work by trigg...

Key Points • External coxa saltans is snapping due to the tensor fascia lata and iliotibial band flipping back and forth across the greater trochanter. • Internal coxa saltans is snapping caused by the iliopsoas tendon. • Intra-articular coxa saltans refers to a variety of intra-articular lesions that can cause painful clicking or popping within the joint. • Coxa vara and reduced bi-iliac width...

The “external structure” in an object oriented system refers here to the graphs of objects and classes. The class structure graph or class model is derived from the object structure graph or object model, and in this operation structural information is lost, or never made explicit. Although object oriented programming languages capture the class model as declarations, contradictory assumptions ...

Self-retaining barbed sutures, innovations for nonsurgical facial and neck rejuvenation, are currently available as short APTOS threads or long WOFFLES threads. The author uses APTOS threads for malar rounding, facial tightening and firming, and uses WOFFLES threads as a sling, suspending ptotic facial tissues to the firm, dense tissues of the temporal scalp.
