Biofuel Production and Its Impact on Global Food Security: A Review Article
Authors: Mahmood Abdulrahman R. , Abdullah Mohamad R. , Khalaf Husam S.
Published: June 2022

The aim of this study is to shed light on the importance of biofuels as an alternative to conventional energy, in addition to the importance of preserving agricultural crops, which are the main source of this fuel, to maintain food security, especially in developing countries. The increase in global oil prices, in addition to the fear of global warming, are among the main factors that draw the world’s attention to searching for alternative sources of traditional energy, which are sustainable on the one hand, and on the other hand reduce carbon emissions. Therefore, the volume of global investment in renewable energy in general, and in liquid biofuels and biomass in particular, has increased. Global fears emerged that the excessive conversion of large farms suitable for growing food to energy production would threaten global food security. In the first ten years of the new millennium, biofuel production increased fivefold, and the largest increase in biofuel production was recorded in 2007-2008, coinciding with a sharp rise in food prices. Compared to the average food prices in the period 2002-2004, the average global prices of cereals, oils and fats traded were 2 to 2.5 times higher in 2008, this continuous increase in the use of food crops to produce biofuels has reflected on global food security. Accordingly, this review article will address previous studies on biofuel production; identify the theoretical framework for the concept of biofuels and its characteristics, and the relationship between biofuels and food security. In this study, we presented biofuels, which are considered one of the important categories in the field of renewable energy and its environmental and economic effects, as well as the experiences of some countries in its production, and the possibility of benefiting from the natural resources available for its production. We will discuss the scientific (chemical) principles of biofuel production.

These mainly conclusion notes depended upon Technetium oxidation state, heteroatoms presence, surface properties besides bio-target specifications, concentration, exposure time, genetic factors of human, and health problems.
La deuda de los situacionistas con el pueblo gitano
Authors: Botana Iglesias Cristina
Published: June 2022

En la segunda mitad del siglo XX se articularon múltiples críticas al urbanismo cartesiano del Movimiento Moderno. La vanguardia Situacionista desarrolló su Urbanismo Unitario inspirándose en las expresiones territoriales de los grupos itinerantes de Rroma europeos. Sin embargo, no lograron abandonar una mirada colonial y primitivista hacia el Pueblo Gitano, cuyo pluriverso todavía es perseguido. El artículo se apoya en una discusión existente sobre dicha conexión y plantea una deuda epistemológica entre las utopías situacionistas y el Pueblo Gitano. Mediante la lectura contrastada de diversas fuentes situacionistas y de otras autorías relacionadas, se identifican los puntos de encuentro y las divergencias entre las propuestas urbanas de la Internacional Situacionista y la territorialidad romaní, analizándolas a partir del concepto de extractivismo epistémico y la crítica decolonial. La investigación se completa con la experiencia de la autora en las luchas de la población gitana residente en asentamientos informales de Galicia. El urbanismo crítico situacionista continuó siendo etnocéntrico, patriarcal y antigitano debido, en parte, a la explicación histórica de las desigualdades urbanas según el eje clase-pobreza. Esta negación contribuyó a la deshumanización extractivista de los Rroma que aún hoy nos impide construir modelos urbanos emancipadores que incorporen los saberes inferiorizados.

La revolución del sonido, Salvador Allende, la Unidad Popular y la adquisición y gestión de las radios Portales, Corporación y Magallanes
Authors: Salgado Muñoz Alfonso
Published: June 2022

Este artículo examina la adquisición y gestión de tres estaciones de radio por parte de la izquierda chilena, en el marco de la vía chilena al socialismo: Portales, Corporación y Magallanes. Salvador Allende jugó un rol destacado en la primera, cuyas acciones fueron compradas por miembros de su círculo íntimo. Las otras dos fueron adquiridas y administradas por los principales partidos de izquierda (el Partido Socialista y el Partido Comunista de Chile) en cuanto personas jurídicas o por miembros de estos partidos en cuanto personas naturales. El artículo demuestra que, pese a la retórica grandilocuente de la época y a los acalorados debates en torno a la socialización de los medios de comunicación, los líderes de la Unidad Popular prefirieron utilizar los mecanismos legales existentes y hacer pesar su poder de compra para ampliar su influencia en la esfera pública.
La historiografía española a través de Castilla. Un estudio de caso a partir de los pensionados vinculados al Centro de Estudios Históricos (1910-1936)
Authors: Sanz Simón Carlos , Sonlleva Velasco Miriam
Published: June 2022

En el seno de la Junta para la Ampliación de Estudios, el Centro de Estudios Históricos llevó a cabo una prolífica trayectoria de internacionalización de una élite académica de investigadores e investigadoras en España durante el primer tercio del siglo XX. Dirigido por Ramón Menéndez Pidal, esta institución supuso una alternativa a las instituciones clásicas en el área y ejerció un papel protagonista en la formación de múltiples profesionales más allá de las fronteras nacionales. En el caso del presente estudio, nos centramos en estudiar las líneas temáticas desarrolladas por aquellos profesionales de la disciplina histórica que, desde la región de Castilla y León, obtuvieron una o varias pensiones de la Junta durante la trayectoria de esta. Los resultados muestran, principalmente, el interés identitario de los estudios de vocación nacional sobre la influencia y aportaciones de España en contextos internacionales y, por otro lado, la predominante masculinización de este sector.
Leyes de escasa aplicación. El sorteo de las normas de comportamiento personal para los magistrados de la audiencia de Lima (siglo XVII)
Authors: Jiménez Jiménez Ismael
Published: June 2022

En su afán por mantener el mayor control posible sobre la administración de las Indias, la Corona creó un cuerpo normativo que rigiese el comportamiento de sus magistrados. Pero este conjunto, conocido como officium iuducis, fue rápidamente sorteado por los miembros de la Audiencia de Lima. Así, los togados acabaron emparentando entre sí y con familias poderosas del territorio, creando redes clientelares con el objetivo de aumentar su estatus sociopolítico y su patrimonio material. Para ello, los magistrados contaron con la connivencia de una monarquía en apuros económicos que no dudó en obviar algunas leyes a cambio de una buena cantidad de pesos.

Research on finished product warehouse inventory based on spatial segmentation
Authors: Sun Shunkai , Li Jie , Xu Qi , Chi Yingxiao , Shen Miaojie , Lin Yizhen
Published: June 2022

This paper proposes a finished product elevated warehouse inventory based on space segmentation, which does not need to control the low storage capacity in advance, nor does it need to stop the inventory, and can use the stacker to carry out the handling task when it is idle. Taking the finished product elevated warehouse of 8 roadways and 9 floors as an example, the inventory work of two floors can be completed every working day, and the inventory work of the whole reservoir area can be completed in 4.5 working days. The first step is to complete the division of the roadway by layer, and then move the finished product pallets of the layer requiring inventory to other layers. After WMS completes the clearance and transportation of all finished product pallets of this layer, the warehouse management personnel will enter the warehouse to manually verify the retention of finished product pallets. This step can ensure that there are finished product pallets in the cargo location with information. Then cooperate with the comparison of finished product pallets in the delivery area of finished product warehouse to realize this step, which can ensure the consistency between information and physical objects. The results show that this inventory method can completely replace the existing complicated manual inventory business, effectively realize the inventory work of finished product elevated warehouse, and provide an accurate and efficient inventory scheme for similar logistics elevated warehouse.

Published: June 2022

Aiming at the problem that it is difficult to determine the picking location for the picking robot, precise positioning of picking grapes based on Mask-RCNN network and Cannylines detector is proposed in this paper. Firstly, the grape images under shading, direct sunlight and backlight conditions are collected, and grape images are marked with masks to make grape data sets. Then, based on the Mask-RCNN network training data set, the trained model is used to identify the grapes, and the box of framed grape cluster and the mask approximately equal to the size of grape cluster are obtained. Then, the AOI of main stem and centroid of grape cluster are calculated according to the obtained box and mask, the obtained AOI is equalized. Finally, the Cannylines detector based on Bilateral filtering is used to detect the line segment of main stem in the AOI, and the picking location is obtained according to the minimum distance between the centroid and the line segment. 150 images from the test set were used for the experiment, with 50 images selected from each type of light, including shading, direct sunlight and backlight. Experiments show that the accuracies of picking positioning under the three types of light conditions, are 0.900, 0.920, and 0.860, respectively. This method can provide precise picking location information for the grape picking robot.

Authors: Yang Menglin , Lu Yiqing
Published: June 2022

The purpose of this paper is to construct a more accurate behavior matrix by using fine-grained aspect level emotion analysis method. Firstly, LDA topic extraction model is used to extract the topic of online review text, and the concerned attributes are extracted. According to the characteristics of online comments, a BERT emotion analysis model with enhanced pooling was proposed. Activation function layer and max-average pooling layer were designed to solve the over-fitting problem of BERT model in the process of emotion analysis. Finally, by combining LDA extraction results and AP-Bert sentiment analysis results, the proportion matrix is obtained. Experimental results show that the accuracy, recall rate and AUC value of AP-Bert model are better than those of the same type of model and original BERT model.

Published: June 2022

For effective and quick selection of hard point coordinate parameters of suspension to improve the handling stability of vehicles, an optimization method was put forward to some certain suspension system by combining the response surface method and NCGA algorithm. A dynamics simulation model was established first to the Macpherson suspension system of some certain mini-van and the sensitivity analysis was carried out to hard point coordinates of the corresponding suspension to find the coordinate parameters whose sensitivities are higher; moreover, an approximate mathematical model was established between the wheel alignment parameters and the selected coordinate parameters in accordance with the response surface method and the corresponding accuracy verification was carried out; and the positioning parameters were grouped rationally and the unified objective function was established by utilizing the direct weighting method; in addition, optimization design was carried out to the established objective function by combining the neighborhood cultivation genetic algorithm (NCGA). Results indicate that the optimized positioning parameter variables are reduced in different degrees so as to further improve the handling stability of vehicles and verify some certain effectiveness of our methods.
Research on Closed-loop Control of Step Motor Based on Magnetic Encoder
Authors: Tang Sai , Yu Yuanhua
Published: June 2022

Stepper motor is an actuator for converting electric pulse signal into angular displacement, which is characterized by no cumulative error, low mature price and good stability, which is widely used in various industrial environments. However, its disadvantage is also very obvious, that is, can only open loop control, the motor can only passively rotate according to the signal and cannot effectively feedback control.If closed-loop control is required, servo motors with higher price and larger volume are required. In order to solve this problem, this paper refits the stepping motor with the help of the characteristics of the magnetic encoder, so as to realize the closed-loop control of the stepping motor.
Research on Sports Video Content Analysis Method Based on Clustering Extraction Algorithm
Authors: Wang Yu , Mei Zhu , Yu Tianbo
Published: June 2022

The algorithm first uses the time domain information of the sports video image to segment the foreground image containing multiple sports targets through sample variance for background modeling. Then the spatial connectivity rate of pixels is defined, and the initial clusters are adaptively split and merged. The self-organizing iterative clustering algorithm can complete the segmentation of multiple moving targets without setting the number of clustering divisions in advance. Experimental results prove that the algorithm has a good segmentation effect on multiple moving targets, and the segmentation results are consistent with the judgment of human vision. The use of spatial connectivity information makes the algorithm iteratively converge fast and has good real-time performance.
