Objective: To describe the methodology for determining the feasibility of producing electricity through the use of wind energy, taking into account the data of the wind resource and the use of a low-power commercial wind turbine to carry out the energy conversion.

Methodology: For this study the data supplied by the meteorological station of the Camilo Daza airport in the city of Cúcuta was evaluated over a period of 5 years, including from the year 2010 - 2014.

Results: The WINDSPOT 7.5 commercial wind turbine was selected kW to establish the production of energy based on the data supplied by the station.

Conclusion: With the analysis of the data provided, it was determined that the implementation of a wind station in the aforesaid area is not feasible given the fact that  wind speeds are not within the recommended range, which must be higher than 5 m / s.

Objective: The present investigation is focused on physically and mechanically characterizing multiple Samples of the coal waste belonging to the municipality of Lenguazaque (Cundinamarca), with the purpose of identifying the possible use of this material in engineering, especially in road infrastructure works.

Methodology: Normative foundations were used, techniques that generated results and information provided by the Ministry of Mines who indicate that the contribution of mining to the growth of the country's economy has shown high growth in recent years, which contrasts with the negative effect that this practice entails on the environment, taking into account that in the extraction of coal there are solid residues resulting from the exploitation of this mineral, these residues are called "sterile coal", which are mostly removed from the carbon so as not to affect the energy potential of the product.

Results and conclusions: The results of the research are encouraging since its characteristics place the material as an alternative for the construction of low traffic road structures.

Objective: To take advantage of the fruit of the Tree of Bread (Artocarpus altilis), to obtain nutritional flour.

Methodology: The fruit was selected by size and degrees of maturity (indicated by the Grade º Brix measurements), controlling in this way phenomena of enzymatic patching (empardeamiento) during the peeling stages and of the activities prior to drying, which was developed in an oven stainless steel at a temperature between 50ºC and 65ºC.

Results: Grinding was carried out in an industrial hammer mill. In addition, physical-chemical characteristics were established in the fruit in each of the resulting degrees of maturity. As well as the bromatological partial, microbiological and sensorial analyzes.

Conclusion: After comparing the nutritional properties of breadfruit flour with the flours of other vegetable species, this process is indicated as an innovative creative alternative on the use and exploitation of many vegetable species for the formulation and elaboration of suitable processed foods. to provide protein elements, accompanied by non-empty calories.

Objective: To consult the state of management in the supply chains of the textile sector, to recognize the inconsistencies of the supply / demand processes, looking for ways to optimize.

Methodology: The focus of the study was on the Colombian textile sector, highlighting the market; crucial processes of demand / supply management were studied, research evidenced inefficient practices and a projection control problem was recognized in front of the demand, generating planning errors, delivery to outdated times of the budgeted ones, inventories in stocks generating additional costs and damage to the goods.

Results: The proposal of a development, free of licensing oriented to the planning of business resources (ERP), will allow an administrative control in the offer / demand, the use of time will be optimized, systematizing inventory and distribution processes, improving productivity of the industry and decreasing storage costs, the research evidenced these processes as critical points and are systematized effectively by the modular interface, the development will support supply / demand management.

Conclusion: The strength of the implementation of the product is in a service oriented to companies that can access administrative control tools that improve the effective use of their inputs in the supply / demand management.

Objective: To develop the capacity indexes of a process for a polynomial profile in a sauce manufacturing company where it is intended to explain the approaches that are acquired through the application of a statistical control, to improve the productive processes, reducing costs and offering competitive products in the market.

Methodology: The research uses quality techniques, applying methods, analysis, control of variables and characteristics of the product, which applied in combination according to this research form the statistical control of the process.

Results: Based on the limits of specifications, a linear profile was elaborated for the independent variables, establishing a same polynomial linear profile to correlate the study variables (° brix and chloride) for the elaboration of sauces for meats.

Conclusions: This study aims to develop better control, which will help decision making in an effective way in terms of the adjustments to be considered in each process, establishing methods, goals and an exceptional means of verifying the behavior of the system.

Objective: To evaluate the geomechanical and mineralogical properties of the Batolito de Pueblo Bello and Patillal rocks in the northeast of the municipality of El Copey, Cesar and their use for ornamentals, the most influential component of their properties being durability as quality indicators, being able to determine , if the batholith is viable for exploitation.

Methodology: The samples acquired in the field were macroscopically and microscopically identified, identifying physical properties of interest, such as the mineral composition, the state of the rock against the weathering agents and others.

Results and conclusions: The resistance of the rock matrix was established; the previous thing, served to estimate the tentative thicknesses of exploitation, being realized additionally calculations of resources by the method of blocks to be able to have an idea of ??the mining geological potential of the area of ??interest.

Objective: To demonstrate how the student, who is trained in a virtual way can understand and verify the exercises that he has solved on topics of mathematical logic in his independent study through a didactic tool of IT or ICT information technology, called Trust Table.

Results and conclusions: Virtual training should be comprehensive where the student can have, through pedagogical strategies a better absorption of knowledge, where through repetition can master his/her self-learning, this way may have the experience in the use of resources Tic Trush Table as an analytical verification tool of the result of the argument given in the truth table exercises.
