There has been an increase in the consumption of the game meat in Europe. Most of the venison products is consumed in West Europe and Scandinavia. Poland belongs to the states, in which the consumption of venison is on the lowest level (0.08 kg/person). We performed a strategic analysis of the venison market in Poland based on the data obtained by direct interviews. The research was carried out in...

The objective of the study was to identify and analyze long−term trends as well as cyclic, seasonal, and irregular effects in timber volume and prices by means of time series decomposition. The adopted multiplicative model was the product of all the time series components identified using the Census X11 method. The study material consisted of quarterly data on the volume and prices of timber sold...

The study objectives were to identify external sources of financing the nature and forest education and to analyze the level of their use in regional directorates of the State Forests (RDSF) in the years 2006−2016. In addition, we studied the relationship between the amount of external and internal financing. As a data source, we used reports on educational activities of the State Forests for the...

While many institutions, whether industrial, academic, or governmental, satisfy their computing needs through public cloud providers, many others still manage their own resources, often as geographically distributed datacenters. Spare capacity from these geographically distributed datacenters could be offered to others, provided there were a mechanism to discover, and then request these resources...

Several system-level operations trigger bulk data copy or initialization. Even though these bulk data operations do not require any computation, current systems transfer a large quantity of data back and forth on the memory channel to perform such operations. As a result, bulk data operations consume high latency, bandwidth, and energy — degrading both system performance and energy efficiency. In...

Data compression is a promising approach for meeting the increasing memory capacity demands expected in future systems. Unfortunately, existing compression algorithms do not translate well when directly applied to main memory because they require the memory controller to perform non-trivial computation to locate a cache line within a compressed memory page, thereby increasing access latency and degrading...

Off-chip main memory has long been a bottleneck for system performance. With increasing memory pressure due to multiple onchip cores, effective cache utilization is important. In a system with limited cache space, we would ideally like to prevent 1) cache pollution, i.e., blocks with low reuse evicting blocks with high reuse from the cache, and 2) cache thrashing, i.e., blocks with high reuse evicting...

Software lifeguards, or tools that monitor applications at runtime, are an effective way of identifying program errors and security exploits. Parallel programs are susceptible to a wider range of possible errors than sequential programs, making them even more in need of online monitoring. Unfortunately, monitoring parallel applications is difficult due to inter-thread data dependences. In prior work,...

Cache compression is a promising technique to increase on-chip cache capacity and to decrease on-chip and off-chip bandwidth usage. Unfortunately, directly applying well-known compression algorithms (usually implemented in software) leads to high hardware complexity and unacceptable decompression/compression latencies, which in turn can negatively affect performance. Hence, there is a need for a simple...
