Abstract: |
Due to the increasingly competitive environment in the business world, improvements in processes have become an alternative to prevail in the market through the effective usage of resources. Such is the case of the organization under study, where the concept and/or idea has been deeply-rooted and become part of the everyday tasks of each of its areas. In this order of ideas, the company under study set the goal of implementing a manufacturing cell for the area of grinding knives, which is expected to significantly reduce the man-hours needed for production. To achieve this, the methodology proposed by Socconini (2013) and Villaseñor & Galindo (2007) was adapted. Firstly, it was necessary to use the load balancing technique for packaging activities, reducing timing by 645 seconds per packaging unit, which represents around 1067 hours annually. Secondly, the area's requirements were determined and the space and infrastructure limitations were identified; finally, a proposal was made for a useful manufacturing cell for each type of packaging. With the implementation of the cell a total monetary saving of 133,365.44 Mexican pesos per year is expected. |

Abstract: |
For designing security protocols to achieve confidentiality, authentication, integrity and non-repudiation Cryptographic primitives are used. . There are a number of surveys on security issues on WSNs, which, however, did not focus on public-key cryptographic primitives in WSNs. In this survey, we provide a deeper understanding of public-key cryptographic primitives in WSNs including identity-based cryptography and discuss their main directions and some open research issues that can be further pursued. We investigate state-of-the-art software implementation results of public-key cryptographic primitives in terms of execution time, energy consumption and resource occupation on constrained wireless devices choosing popular IEEE 802.15.4-compliant WSN hardware platforms, used in real-life deployments. |

Abstract: |
One of the skills that must be possessed by market participants in financial markets is the ability to predict trends in price changes in the future well. A market participant in financial markets needs to carry out various analyzes to avoid sustained losses and increase investment portfolios. The analysis that is popularly used by market participants today is technical analysis, one of the drawbacks of technical analysis is that it cannot predict exactly when there will be a large movement in the price of a currency or other investment instruments. This requires market participants to be in front of the monitor screen to monitor price movements. In an intelligent system that is built, with input in the form of economic consensus data, official release data, revised release and the presence or absence of related party conferences on the relevant day processed in the role-based fundamental analysis, outputs can be obtained in the form of spike directions, large spikes, time of spike and estimates the profit. This study uses fundamental analysis formulated with historical data to estimate the direction of the increase in the value of foreign currencies. The results of this study are estimates of the direction of market spike, the size of the market spikeand the duration of the marketspike. This research is expected to help decision-makers or financial market participants to increase investment portfolios and avoid ongoing losses or even bankruptcy. |

Abstract: |
This work devoted to study the behavior of reinforced concrete bubble slabs exposed to fire flame. The experimental work concluded casting and burning nine specimens under static load. The test parameters were; The dimension of specimens was (700x450x80) mm, all specimens have same compressive strength 30 MPa (normal concrete), ball diameter was 40 mm, ratio of reinforcement at top and bottom of slabs 0.00417, fire flame temperature was (200, 300 and 400) ℃, fire flame duration (30 and 60) minutes and concrete cover (20 and 10) mm. the specimens were simply supported in two directions. The test results show that, RC bubble slab exposed to 200℃ at 30 and 60 minutes with 20 mm cover spalling not happened but in specimen with 10 mm concrete cover spalling occurred. All RC bubble slab exposed to 300℃ and 400℃ spalling occurred, damage of spalling for bubble slabs exposed to 300℃ in 30-minute fire duration more than 400℃ by (32 %) otherwise at 60-minute fire duration damage of spalling in 400℃ more than 300℃ by (49 %). Deflection during burning was observed due to static load and elevated of temperature, deflection increase with increase fire flame temperature and duration, increase of fire duration to 60 minute from 30-minute leadto increase in deflection with fire flame rate (200, 300 and 400) ℃ by (57, 79 and 68) % respectively in compassion with slabs exposed same fire rate at 30 minute. |

Abstract: |
This study is conducted to investigate effect of footing thickness(100,120 140 mm) and steel fiber ratio (0,1,1.5 %) on punching shear failure of self-compacting concrete(SCC)pad footing. The specimens were supported on a bed of steel(car)springs and loaded by vertical centric force. The results showed that the first crack load and ultimate load, ductility and strength improve as the thickness increase and failed by punching shear failure. After adding steel fiber with different ratio the result showed that the first crack load , ultimate load , strength and ductility increase with increasing of steel fiber ratio and failed by flexural punching failure, Also, It is noticed that failure of all specimens without steel fibers was sudden and brittle as compared to those with steel fibers in which failure was gradually. |

Abstract: |
This study presents the integration of two tools little explored by Small and Medium Enterprises in Mexico: Lean systems with Ergonomics; a case study of application is documented where the main tools used were Value Stream Mapping, SIPOC, Kaizen, REBA Method and NIOSH. As a result, the activities with the greatest risk, waste of time and movements, postures and inadequate procedures were obtained during their operations that delay and affect the flow of the process. After implementing the proposals, a reduction was presented by 33.18% of the cycle time, making the process more efficient. This app can give a new approach to use in improving sME productivity. |

Abstract: |
Steam power plant (PLTU) is a machine that can convert chemical energy from fuel into heat energy that is transferred into a boiler filled with water so that it becomes kinetic energy in steam, and then the steam is used to move the piston back and forth, then rotate the crankshaft then rotating the generator so that it produces electricity. This study aims to produce a prototype of steam power plant product that can be used as a practicum tool for students so as to improve students' scientific knowledge and thinking abilities in learning energy conversion machines. This research was conducted in two stages, namely (1). Design and manufacture of mini steam engine components, (2). Testing a prototype of a mini steam engine is to determine the output power, heat rate and thermal efficiency.
Based on the results of research conducted, that the mini PLTU prototype can produce electrical energy so that it can be used for media for practicum in mechanical engineering students, is especially in energy conversion and steam engine courses. Analysis of the performance of a mini steam engine obtained the highest output power occurred at 1113.36 rpm with 14 units of lamp load with a value of 0.000302 kW; The highest heat rate occurs at a steam temperature of 107.4 oC with a heat rate of 9877,456; and the highest thermal efficiency occurs at a steam temperature of 97.6 oC with a thermal efficiency value of 1.470%. |
