Faculty of Engineering, Mathematics and Science Department of Computer Science and Statistics Master of Science in Computer Science Scientific computing with non-standard floating point types May 2015 Author: Vlăduţ Mădălin Druţa Supervisor: Dr. David Gregg This study examined the possible use of non-standard floating point types for scientific computing. The question of this thesis is: “Is the...

It is proposed to add to the C++ standard optional floating-point typedefs having specified widths. The optional typedefs include float16_t, float32_t, float64_t, float128_t, their corresponding least and fast types, and the corresponding maximumwidth type. These are to conform with the corresponding specifications of binary16, binary32, binary64, and binary128 in IEEE_ floating-point format. T...

Firms sometimes write price lists or catalogs for their exports, so they set prices for a period of time and do not adjust prices during that interval in response to changes in their environment. The firm sets the price either in its own currency or the importer’s currency. This paper draws a simple link between the choice of currency and the pricing decision of a firm that changes prices in re...

Traditionally, policymakers and financial markets have regarded the “core” consumer price index (CPI) as a key inflation indicator. The core CPI, a special index published by the Bureau of Labor Statistics (BLS), excludes the volatile prices of food and energy. In excluding these components, BLS recognizes that prices that swing dramatically in response to unusual shifts in weather and other un...

For utility maximization problems under proportional transaction costs, it has been observed that the original market with transaction costs can sometimes be replaced by a frictionless shadow market that yields the same optimal strategy and utility. However, the question of whether or not this indeed holds in generality has remained elusive so far. In this paper we present a counterexample whic...

This paper examines the equilibrium growth effect of money/inflation within a standard one-sector AK model of endogenous growth with the most generalized cash-in-advance constraint and wealth-enhanced preferences for social status. We show that the sign for the correlation between money and output growth depends crucially on (i) the liquidityconstrained ratio of consumption to investment expend...

Modified BG Prasad socioeconomic scale is widely used to determine the socioeconomic status of study subjects in health studies in India. It is an income-based scale and, therefore, has to be constantly updated to take inflation and depreciation of rupee into account. The Consumer Price Index (CPI) for industrial workers (IW) is used to calculate updated income categories for January 2014. Deta...

We address the single source shortest path planning problem (SSSP) in the case of floating point edge weights. We show how any integer based Dijkstra solution that relies on a monotone integer priority queue to create a full ordering over path lengths in order to solve integer SSSP can be used as an oracle to solve floating point SSSP with positive edge weights (floating point P-SSSP). Floating...

To improve economic growth acceleration, the Nigerian government should continue to formulate and implement several policies including exchange rate policy regimes. Exchange regime of any could be a fixed when price country’s currency in terms another is value by monetary authority; it floating left determined forces demand supply, while managed-floating undertaken there an element both Followi...

background: floating knee, referred to as ipsilateral fractures of the femur and tibia, is usually associated with several complications and mortality. this study was designed to present our experience with treatment of this injury throughout; age, sex, mechanism of injury, associated injuries, method and results of treatment, and complications of floating knee are discussed. materials and meth...
