We study the maximum duo-preservation string mapping (Max-Duo) problem, which is the complement of the well studied minimum common string partition (MCSP) problem. Both problems have applications in many fields including text compression and bioinformatics. Motivated by an earlier local search algorithm, we present an improved approximation and show that its performance ratio is no greater than...

This study utilized a data envelopment analysis model to the performance persistence of 16 asset management institutions. When we evaluate based on capital efficiency (or productivity) ratio, earnings before interest, taxes, depreciation, and amortization (EBITDA) margin, return investment (ROI), find that only one bank has consistently outperformed its peers every year from 2014 2019. add tax ...

Problem. One of the areas developing energy saving when using machines and mechanisms is recovery used for purpose reuse. At same time, potential accumulated by massive or kinetic moving machine elements used. Goal. The work to reveal main advantages principle operation pneumatic damping system generation. Methodology. methodological basis analysis, comparison generalization existing scientific...

In recent years, measuring and analyzing productivity changes is the main focus of variousresearches who study performance of organizations. All through widespread application ofMalmquist Productivity Index, different types of data should be considered thoroughly,otherwise any defective study of the related data and deciding factors may yield poor results.Practical Malmquist Productivity Index ...

Recent interactive ray tracing performance has been mainly derived from the use of ray packets. Larger ray packets allow for significant amortization of both computations and memory accesses; however, the majority of primitives are still intersected by each ray in a packet. This paper discusses several methods to cull entire ray packets against common primitives (box, triangle, and sphere) that...

Organization and method of assembly management report using a definition of EBITDA indicator (Earnings before interest and tax, amortization and depreciation) are considered on the practical example of Kherson river port’s activity. The process of constructing a multidimensional model, that is necessary for determining EBITDA of integrated accounting using the program "1C: Accounting for Ukrain...

Amortization has been underutilized in the design of persistent data structures, largely because traditional accounting schemes break down in a persistent setting. Such schemes depend on saving “credits” for future use, but a persistent data structure may have multiple “futures”, each competing for the same credits. We describe how lazy evaluation can often remedy this problem, yielding persist...

Given two genomic maps G1 and G2 each represented as a sequence of n gene markers, the maximal strip recovery (MSR) problem is to retain the maximum number of markers in both G1 and G2 such that the resultant subsequences, denoted as G ∗ 1 and G ∗ 2, can be partitioned into the same set of maximal strips, which are common substrings of length greater than or equal to two. The complementary maxi...

We analyze the ability of earnings and non-earnings performance metrics to explain stock returns for industries where we identify, ex ante, an allegedly preferred (for valuation purposes) performance metric. We identify three industries each where earnings before interest, taxes, depreciation and amortization (EBITDA) and cash from operations are preferred, and three industries where specific n...

Estimating the value of business process management (BPM) technology is a difficult task to accomplish. Computerized business processes have a strong impact on an organization, and BPM projects have a long-term cost amortization. To systematically analyze BPM technology from an economic-driven perspective, we are currently developing an evaluation framework in the EcoPOST project. In order to e...
