appropriate function of active management in common investment funds function depend on factors such as diversification, identification papers unrealistic pricing, market timing, and so on. market timing are include changing the portfolio investment funds and market indices such as short-term bonds and make an asset depends on whether the market is expected in the whole of the assets to make be...

introduction criteria for starting weight-bearing on the heel with a symptomatic calcaneal insufficiency fracture have not yet been reported. case presentation we describe a rare case of a 52-year-old woman with a calcaneal insufficiency fracture who sustained a second ipsilateral calcaneal insufficiency fracture within a short time span. the initial fracture was not evident radiographically, b...

methanol as a biofuel is an environmental friendly substitute to pure diesel and can be obtained from biomasses. use of biofuels such as methanol for combustion process is associated with positive environmental impacts. using pure methanol or blended with diesel fuel in automotive has been proposed by researchers. in this paper, methanol was injected into combustion chamber of a ism 370 hd dies...

Timing analysis plays a vital role in chip design, which analyze whether a chip design meets the timing constraints. The main objectives of timing analysis are speed and accuracy. There are two engines for timing analysis namely Statistical Timing Analysis (STA) and Statistical Static Timing Analysis (SSTA). VLSI CAD has been gaining a lot of interest in both STA and SSTA. As technology continu...

The proposed approach for the statistical static timing analysis (SSTA) problem of latch-based sequential circuits under process variations was investigated. The proposed statistical positive cycle detection algorithm is developed in Section 2. Practical implementation considerations are presented in Section 3. Experimental results are shown in Section 4. Based on the current progress, the futu...

We describe a polynomial-time algorithm for min-max timing simulation of combinational circuits. Our algorithm reports conservative bounds on the propagationdelays from each primary input to each gate, for use in the timing verification of fundamental-mode asynchronous circuits. A new reconvergent fanout analysis technique is presented. Our algorithm produces more accurate results than previous...

In statistical methods, such as statistical static timing analysis, Gaussian mixture model (GMM) is a useful tool for representing a non-Gaussian distribution and handling correlation easily. In order to repeat various statistical operations such as summation and maximum for GMMs efficiently, the number of components should be restricted around two. In this paper, we propose a method for reduci...

Timing diagrams are popular in hardware design. They have been formalized for use in reasoning tasks, such as computer-aided veriication. These eeorts have largely treated timing diagrams as interfaces to established notations for which veriication is decidable; this has restricted timing diagrams to expressing only regular language properties. This paper presents a timing diagram logic capable...
