Manufacturing processes that consist of time series data are frequently monitored by forecast-based quality control schemes. These control schemes are based on the application of a time series forecast to the process and monitoring the resultant forecast errors with a control chart. This study compares the performance of the Individuals control chart, the Cumulative Sum (CUSUM) and the Exponentially Weighted (EWMA) chart in their ability to detect the presence of changes in the process mean (step shift) and additive outliers in an autocorrelated process. The criteria used are the Average Run Length (ARL) and Cumulative Distribution Function (CDF) of the run lengths. The CDF is offered as an alternative performance evaluation criterion, for forecast-based schemes. The Individuals chart offers the greatest probability of early detection of a step shift and an additive outlier in an autocorrelated process, based on the CDF criterion.

Keywords: control charts, process control, quality engineering.

A front suspension is capable of absorbing the vibrations produced at wheel due to irregular ground surface on which rider ride the bike. By this way, vibrations do not be transmitted to the bike rider. Conventional Front fork system uses helical spring to absorb the vibrations which include major cost of Suspension system & also increase the weight of the Front fork unit. In this invention, the front fork includes two vertical leg assemblies as a shock absorbing unit which is made by a group of components that operates by means of suspension oil & a gaseous fluid. Internal floating piston is used to separate an oil chamber from the other gaseous fluid chamber. The front fork also includes a simple mechanical blocking system which is further used to generatedamping force.

Keywords: Front suspension, absorbing vibration, helical spring, suspension oil, gaseous fluid, Internal floating piston, Damping force

Reverse Engineering is the process of obtaining a geometric CAD model from 3D scan points cloud which is acquired by scanning an existing part. 3D virtual models can be completely generated through reverse engineering. There are various applications of reverse engineering such as in manufacturing, industrial design, jewellery reproduction and design, development and inspection of parts, etc.., A physical model is taken and scanned to get point cloud. This data is processed in different stages to finally get the CAD data. Dimensions, features, surfaces, etc.., can be reconstructed for the component using Reverse Engineering.

Keywords: Reverse engineering, bevel gear, 3D scanning, point cloud, polygon model, NURBS surfaces.

During centuries, Moroccan olive oil sector has played an important role in rural communities development, as a source of income and employment for a large segment of farmers. In 2019, Morocco is ranked 4th producer of olive oil in the world-wide thanks to its geographical position, climate conditions and to new agriculture economic policy called 'Moroccan Green plan'. Hence, these characteristics explain the importance and need of studying consumer' behaviours to establish adapted strategy of commercialization in local market. The main objective of this paper is the investigation of factors influencing consumer preferences toward olive oil. Data were collected by face-to-face interview, a total of 313 adult consumers interview in Fez-Meknes region were done.......

Keywords- Consumer behaviour, influencing factors, preferences, Olive Oil, Morocco.

Data mining, the extraction of hidden predictive information through large databases, can be an effective new technology with good potential to assist organizations gives attention to important information in their data warehouses. Data mining tools estimate future trends as well as behaviors, enabling businesses to produce proactive, knowledge-driven decisions. The automated, prospective analyses proposed by data mining move beyond the studies of past events offered by retrospective tools typical of decision support systems. Data mining tools could answer business questions that typically were too time intensive to solve. They scour databases for hidden patterns, finding predictive information that experts may possibly miss as it lies outside their objectives. This paper targets on several data mining methods to recognize effective cluster techniques for big data cluster formation.

The big project requires special structures dive important of this project. The special architectural requirements for these projects need special structural design, for high performance in both dynamic and static cases. Panelled beams with circular edge beam has special behavior under seismic loads, with different panelled beams configurations with circular edge beam will be studied to make the most suitable panelled beams arrangement with acceptable performance under seismic loads. Six 3D panelled beams with circular edge beam with 6 stores with different panelled beams arrangements (skew panelled beams or perpendicular panelled beams configurations) studied to show the ideal performance of the structures subjected to earthquakes. Skew panelled beams supported on circular beams for angles 30o, 45o and 60o are not suitable for those structures subjected to earthquakes with comparison with perpendicular panelled beams supported on circular beam which performed well under seismic loads, and the panelled beams supported on circular beam resist tensional forces results from earthquakes.

Gully erosion has remained an intractable problem in the South East Region of Nigeria despite the huge sums of money being spent to curb the menace by the Federal and State government. This study explores the causes and consequences of gully erosion in South Eastern States of Nigeria. It identifies some natural causes (precipitation, topography and soil properties) as well as human causes (vegetation clearance, uncontrolled urbanization, road construction, and poor farming practices) of gully erosion. It also enumerates the consequences of gully erosion in the South Eastern Nigeria. The study highlights the current efforts undertaken to address gully erosion in the South East Region of Nigeria..........
