An algorithm that constructs a continuous piecewise linear representation, subject to a certain slope/segment length constraint, of a given set of data is described. The algorithm yields an optimal or near optimal representation, subject to this constraint, in the L∞ norm and does so in at worst O(nK) time, where n is the number of data points and K the number of segments. The constraint is det...

We describe a computer algorithm designed to calculate the optimal energy extraction in the form of heat used for steam raising from chemical processes. The concepts are illustrated using chemical plant stream data in a process with multiple distillation columns. Pinch analysis is first applied to find the grand composite curve (GCC) of the problem, which is then used by the algorithm to determ...

Temperature rise is a concern for future agriculture in different regions of the globe. This study aimed to reveal changes and variabilities minimum temperature (Tmin) maximum (Tmax) monthly, seasonal, annual scale over Bangladesh using 40 General Circulation Models (GCMs) Coupled Model Intercomparison Project Phase 5 (CMIP5) two radiative concentration pathways (RCPs, RCP4.5 RCP8.5). The stati...

Previous research has documented a tight positive relationship between vegetation activity and growing season air temperature in China’s temperate zone (TC). However, this may change over time following alternations other environmental factors. Using the linear regression analysis moving windows based on partial correlation method, temporal variations of responses NDVI to rising during 1982–201...

Trends in seasonal mean values of maximum and minimum temperature are analysed the Spanish mainland from new MOTEDAS_century database. This data set has been developed combining digitalized archives Meteorological Agency (AEMET) with information retrieved Annual Books published by former dating back to 1916, covers period 1916–2015. In all four seasons, (Tmax) (Tmin) increased. The raising occu...

In the last 20 years many proposals have been made to incorporate non-monotonic reasoning into description logics, ranging from approaches based on default logic and circumscription to those based on preferential semantics. In particular, the non-monotonic description logic ALC+Tmin uses a combination of the preferential semantics with minimization of a certain kind of concepts, which represent...

mixing at nighttime should play a dominant role by transferring more heat from the atmosphere to the near-surface to warm the Tmin. Further analyses using the high resolution CFMIP2 output also support the CMIP5 results about the connections of the biases between the simulated turbulent mixing and the temperature diurnal cycle. The large inter-model variations of the simulated temperature diurn...

The binary phase diagram CaF2–SrF2 was investigated by differential thermal analysis (DTA). Both substances show unlimited mutual solubility. An azeotropic point showing a minimum melting temperature of Tmin = 1373 C for the composition Ca0.582Sr0.418F2. Close to this composition, homogeneous single crystals up to 30mm diameter without remarkable segregation could be grown by the Czochralski me...
