Chaos and Boundary Values Problems of Dynamical Systems

The boundary values of problem that are determined from observations play a decisive role in solving any problem in mathematical models of dynamic systems. They lead to the search of answer to the following questions: From observations, is it possible to find such boundary values, which could become the guarantor of the existence of smooth…

On ‘Big’ Boolean-Equation Solving and Its Utility in Combinatorial Digital Design

This chapter considers the problem of solving a system of Boolean equations over a finite (atomic) Boolean  algebra  other  than  the  two-valued  one.  A  prominent  “misnomer”  in  mathematical  and engineering  circles  is  the  term  ‘Boolean  algebra’.  This  term  is  widely  used  to  refer  to  switching algebra, which is just one particular case of a ‘Boolean…

Continental Application of Foamed Concrete Technology: Lessons for Civil Engineering Infrastructures Development for Africa

The properties of foamed concrete as a variable density concrete, is now being tapped for effective application in the global construction industry. Foamed concrete is applicable in various continental climates. In hot continental climates, with very hot days and cold nights with temperatures of 90°C and 10°C respectively, it is successfully used in Kazachstan, Iran,…

Hypothetical Approach in Determining Vibrations of Periodic Cutting Tool Holder

Vibration is a standout amongst the most irritating issues looked amid the metal cutting activity, and it happens much of the time in assembling ventures. The vibration level relies upon a wide range of parameters, for example, material sort, inflexibilityof tooling structure, cutting  information and task mode.  In  processing,  the  slicing  procedure  exposed  to  the …

Water Stress on Springs of Lesser Himalayan Region

The lesser Himalayan range dominantly consists of tectonic setting that is characterized by multiple deformations  resulting  in  superimposed  folding  and  repeated  faulting  and  thrusting.  The  rocks  of lesser Himalayan are highly weathered and immensely fractured that helps them to act as filter and regulates the groundwater paths for the springs as conduit (rapid) or diffused…

Hybird, Solar and Biomass Energy System for Heating Greenhouse Sweet Coloured Pepper

The  main  drawback  of  greenhouse  heating systems  based on  solar  energy  is  the  unavailability  at nighttime and the variation of its value from hour to hour and month to another during daylight-time. However, use the combination of two-source of renewable energy (solar energy and biomass heat energy) successfully provides appropriate amount of heat energy for…

Air Temperature Time Series Trend Analysis of Upper Ganga Canal Command by Mann Kendall Test

Worldwide  climatologists  are  investigating  to  find  a  possible  relation  of  climate  change  with anthropogenic behavior by studying trends in different climatic parameters. However, the changes in temperature are not equal for all regions especially in India and have localized intensity and must be quantified locally to manage the natural resources. Aim of the study is…
