Hardware-Based Architecture for DNN Wireless Communication Models
Authors: Tran Van Duy , Lam Duc Khai , Tran Thi Hong
Published: January 2023

Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO OFDM) is a key technology for wireless communication systems. However, because of the problem of a high peak-to-average power ratio (PAPR), OFDM symbols can be distorted at the MIMO OFDM transmitter. It degrades the signal detection and channel estimation performance at the MIMO OFDM receiver. In this paper, three deep neural network (DNN) models are proposed to solve the problem of non-linear distortions introduced by the power amplifier (PA) of the transmitters and replace the conventional digital signal processing (DSP) modules at the receivers in 2 × 2 MIMO OFDM and 4 × 4 MIMO OFDM systems. Proposed model type I uses the DNN model to de-map the signals at the receiver. Proposed model type II uses the DNN model to learn and filter out the channel noises at the receiver. Proposed model type III uses the DNN model to de-map and detect the signals at the receiver. All three model types attempt to solve the non-linear problem. The robust bit error rate (BER) performances of the proposed receivers are achieved through the software and hardware implementation results. In addition, we have also implemented appropriate hardware architectures for the proposed DNN models using special techniques, such as quantization and pipeline to check the feasibility in practice, which recent studies have not done. Our hardware architectures are successfully designed and implemented on the Virtex 7 vc709 FPGA board.

Published: January 2023

Anomaly detection has been known as an effective technique to detect faults or cyber-attacks in industrial control systems (ICS). Therefore, many anomaly detection models have been proposed for ICS. However, most models have been implemented and evaluated under specific circumstances, which leads to confusion about choosing the best model in a real-world situation. In other words, there still needs to be a comprehensive comparison of state-of-the-art anomaly detection models with common experimental configurations. To address this problem, we conduct a comparative study of five representative time series anomaly detection models: InterFusion, RANSynCoder, GDN, LSTM-ED, and USAD. We specifically compare the performance analysis of the models in detection accuracy, training, and testing times with two publicly available datasets: SWaT and HAI. The experimental results show that the best model results are inconsistent with the datasets. For SWaT, InterFusion achieves the highest F1-score of 90.7% while RANSynCoder achieves the highest F1-score of 82.9% for HAI. We also investigate the effects of the training set size on the performance of anomaly detection models. We found that about 40% of the entire training set would be sufficient to build a model producing a similar performance compared to using the entire training set.

Authors: Yang Xiaoyu , Dong Jianqiang , Guo Xiaopeng
Published: January 2023

China has made achievements in SO2 emissions reduction in recent years. However, the emissions of SO2 in northern China remain high, which need to be reduced. To effectively control SO2 emissions in northern China, this paper from the perspective of the coordinated treatment of air pollution discusses the impact of energy consumption, economic development, and environmental regulation on SO2 emissions in 14 provinces and regions by the Spatial Lag Model (SLM), Spatial Error Model (SEM), and Spatial Durbin Model (SDM). The study shows that (1) there is an obvious spatial dependence between SO2 emissions and energy consumption; (2) the increase in the scale of industry enterprise can exacerbate SO2 emissions in local and adjacent regions; and (3) the consumption of electricity suppresses SO2 emissions in the local region, and increases SO2 emissions in adjacent regions, which indicated that the electricity transmission can transfer the emissions of SO2. Therefore, in the treatment of SO2, it is necessary to fully consider the characteristics of SO2 transfer in the electric power industry.
Multidimensional Legal Research on the Transfer of Environmentally Sound Technologies in China
Authors: Zhang Zhenyu , Ren Xumin
Published: January 2023

The transfer of environmentally sound technologies has always been the focus of controversy to combat global climate change. The essence of the transfer of environmentally sound technologies is the coordination of interests among regions, with the aim of mitigating and adapting to global climate change. The realization of environmentally sound technology transfer mainly reflects the game between control and freedom, the coordination of public interests and private interests, and the equilibrium theory of supply and demand. Faced with the current situation of weak laws on the transfer of environmentally sound technologies, it is suggested that China needs to establish and improve the relevant legal system from the four dimensions of technology transfer law, environmental law, intellectual property law, and investment law, improve the legal system to realize the transfer of environmentally sound technology, and strengthen the connection between China’s laws and relevant international law rules. At the same time, in order to improve the management mechanism of environmentally sound technology transfer, it is suggested that China should propose legal measures to optimize the institutional system of environmentally sound technology transfer from three dimensions, namely the state, social organizations, and individuals, and form a governance model of multi-actor cooperative management to promote the transfer of environmentally sound technology between China and other countries to achieve the goal of coping with climate change and to protect the global environment.

Published: January 2023

Overburden strata fracture evolution is critical to dynamic disaster prevention and gas-relief drainage, so it is important to accurately determine the evolution relationships with mining disturbance. In this paper, experiments and numerical simulation were adopted jointly to characterize the time-varying fracture area of overlying strata. The experimental results showed that the roof strata gradually broke and collapsed with coal mining, which indicated the fractures of overburden strata developed in an upward direction. The fracture development causes were explained by numerical simulation, which showed that stress increase exceeded the strength of coal and rock strata, and fractures were formed and expanded. Both experiments and numerical simulation results showed the two sides and the top of fracture areas provided channels and spaces for gas migration and reservoir, respectively. In addition, the breaking angle of overburden strata and the height of fracture areas were analyzed quantitatively. Through microseismic monitoring at the mining site, the fracture scales and ranges of overburden strata were verified by the energy and frequency of microseismic events, which were consistent with the support of maximum resistance. The position of drainage boreholes was considered based on the results of overburden strata fracture evolution. Our study is aimed at promoting coal mining in safety and improving gas drainage with a sustainable approach.

Authors: Mei Tingting , Qin Yi , Li Peng , Deng Yongfei
Published: January 2023

The construction supply chain has many stakeholders and complex and diverse information, which cause various information exchange problems that diminish project management efficiency. Thus, information collaboration is an important factor in the construction supply chain. This study aims to improve the efficiency of project management by analyzing the factors hindering information collaboration in the construction supply chain in order to determine their internal influencing mechanisms. The relevant data of 281 construction employees is collected by questionnaire survey. The relationship among stakeholders (SH), information technology (IT), external stability mechanism (ESM), and information collaboration is then quantitatively evaluated based on the structural equation model (SEM). The results show that stakeholders, information technology, and the external stability mechanism have an influence on information collaboration, while stakeholders do not have a significant influence. Information technology and the external stability mechanism significantly influence information collaboration and provide a mediation role between stakeholders and information collaboration. The innovation of this work is the quantification of information collaboration influencing factors in the construction supply chain and the analysis of its potential path relationship according to the mediating effect test. Its theoretical contribution is to address the research gap in construction supply chain information collaboration and expand the research scope of construction project collaborative management regarding information collaboration. Finally, this work has a practical contribution by providing suggestions for improving the efficiency of building supply information collaboration.

Obesity is increasing in incidence worldwide, especially in women, which can affect the outcome of pregnancy. During this period, viral infections represent a risk to the mother, the placental unit, and the fetus. The Zika virus (ZIKV) outbreak in Brazil has been the cause of congenital Zika syndrome (CZS), with devastating consequences such as microcephaly in newborns. Herein, we analyzed the impact of maternal overweight/obesity on the antiviral factors’ expression in the placental tissue of Zika-infected mothers. We accessed placentas from women with and without obesity from 34 public health units (São Paulo) and from Zika-infected mothers with and without obesity from the Clinical Cohort Study of ZIKV pregnant women (Rio de Janeiro, Brazil). We first verified that obesity, without infection, did not alter the constitutive transcriptional expression of antiviral factors or IFN type I/III expression. Interestingly, obesity, when associated with ZIKV infection, showed a decreased transcriptional expression of RIG-I and IFIH1 (MDA-5 protein precursor gene). At the protein level, we also verified a decreased RIG-I and IRF-3 expression in the decidual placenta from the Zika-infected obese group, regardless of microcephaly. This finding shows, for the first time, that obesity associated with ZIKV infection leads to an impaired type I IFN downstream signaling pathway in the maternal–fetal interface.

Published: January 2023

With the increasing emphasis on the ecology and environment of rivers, the construction of ecological waterway projects has become a development trend in China. In recent years, more and more attention has been paid to the qualitative and quantitative evaluation of the ecological effects of ecological waterway construction. Based on pressure-state-response (PSR) and driver-pressure-state-impact-response (DPSIR) logical frameworks, this paper established a state-pressure-impact-response (SPIR) conceptual model. The model took the river ecology and environment state as the main line, and described the disturbance pressure of the engineering construction on the river state, the impacts of the project on the river comprehensive function, and the positive responses taken in the full lifetime cycle of the project. The analytic hierarchy process (AHP) and fuzzy evaluation model were used to study the changes of the river ecosystem status after suffering from the construction pressure and taking positive responses. Taking the 12.5 m deep water waterway project in the Taicang-Nantong section of the lower reaches of the Yangtze River as an example, the disturbance on the ecology and environment at different stages of the project construction and the effort of relieving the negative impacts of the project on the ecology and environment were evaluated by the health level of the ecosystem. The paper can provide a scientific method for the evaluation of ecological projects in river ecosystems.

Authors: Fontana Carine , Smaniotto Alessandra , Villanova Daniela L.
Published: January 2023

Aços carbono são amplamente empregados na construção civil, especialmente em estruturas metálicas, sendo este material a principal matéria-prima para confecção de estruturas. Entretanto, uma grande desvantagem da utilização do aço carbono é sua baixa resistência à corrosão o que o torna um material suscetível a processos corrosivos. O efeito inibidor do extrato natural de cascas de bergamota (Citrus reticulata) frente ao processo corrosivo de aço carbono ASTM A36 foi investigado por meio de ensaios de perda de massa de corpos de prova por imersão em meio corrosivo, conjugados com análises de isotermas de adsorção. Resultados demonstram que o extrato de bergamota apresenta considerável ação inibidora de corrosão em aço carbono ASTM A36 em meio ácido (HCl 0,1 mol•L-1). O efeito da temperatura foi avaliado, verificando-se que a eficiência de inibição varia consideravelmente com o aumento da temperatura.  A maior eficiência de inibição contra corrosão observada foi de 86 ± 2% em meio ácido, para uma temperatura de ensaio de 30 ºC e concentração de 40g/L de extrato de bergamota.  Além disso, as isotermas de adsorção mostraram que a o melhor ajuste foi para a isoterma de Langmuir, cujo coeficiente de correlação linear encontrado foi de 0,998 indicando que o comportamento do extrato obedece a essa isoterma. Assim, os resultados obtidos sugerem que o extrato de bergamota apresenta potencial para ser empregado na proteção contra a corrosão em aço carbono ASTM A36 em meio ácido.
Adaptability of Common Coastal Wetland Plant Populations to Future Sea Level Rise

Published: January 2023

An accelerating rate of sea level rise (SLR) is causing huge inundation pressure on coastal wetlands worldwide. Vegetation of coastal wetlands plays a key role in stabilizing the coast and accreting sediment in order to mitigate the negative impact of SLR. The ability to accrete sediment is influenced by individual species traits; however, there are insufficient information and indicators to identify differences in the adaptability of various coastal vegetations to SLR at a regional or global scale. Here, the potential adaptation of 27 plant populations in coastal wetlands subject to SLR was evaluated using a compiled global dataset and a marsh equilibrium model. Sediment accretion efficiency differed among plant populations, but most coastal marsh populations and a few mangrove populations had relatively high accretion rates; habitats with high accretion rates will have a better potential to deal with the threat of SLR. These results showed that latitude and efficiency shared a nonlinear relationship, and plant stem density and root structure were among the important factors that influenced the efficiency. Fibrous root plant populations had a greater sediment accretion efficiency than tap root plant populations, and perennial populations had a greater sediment accretion efficiency than annual plant populations. These findings can provide key parameters relating to the sediment accretion efficiency of hydrological and geomorphic models on a global scale. This study offers some novel insights into the dynamic changes in coastal wetlands following SLR that will be particularly useful in devising appropriate strategies for the protection and management of coastal wetlands.

Authors: Fang Xingnan , Zhang Yang , Yu Wei , Chen Xinjun
Published: January 2023

The Humboldt squid
Dosidicus gigas
is a pelagic cephalopod species extensively distributed in the Eastern Pacific Ocean. Geographically separated habitat patterns of
D. gigas
show large spatiotemporal variations due to the distinct different regional environmental conditions. This study explored geographical variation in seasonal habitat of
D. gigas
off Peru and the Eastern Pacific Equator using maximum entropy (Maxent) model, with fishing occurrence data and environmental variables including sea surface temperature (SST), sea surface salinity, net primary production (NPP), photosynthetically active radiation (PAR), chlorophyll
a
concentration, eddy kinetic energy, and sea level anomaly. Results indicated that all the environmental variables exhibited conspicuous seasonal and geographical differences off Peru and the Eastern Pacific Equator. On the basis of the percent contribution from the Maxent model, seasonal and spatial extents of habitat were largely explained by SST, NPP, PAR, and eddy kinetic energy in the Eastern Pacific Equator and SST, sea surface salinity, NPP, and PAR off Peru. Suitable ranges of each environmental variable differed between regions and were controlled by the seasonal variability. Furthermore, movement patterns of longitudinal and latitudinal gravity centers of fishing effort of
D. gigas
were consistent with spatial and temporal distribution of suitable habitats but showed dramatically geographical variations off Peru and the Eastern Pacific Equator. Our findings highlighted Maxent mode’s ability in exploring Humboldt squid habitat hotspots in the Eastern Pacific Ocean and suggested that constructing the habitat model for
D. gigas
should consider the geographical differences under environmental conditions.

In situ self-assembly of semiconducting emitters into multilayer cracks is a significant solution-processing method to fabricate organic high-
Q
lasers. However, it is still difficult to realize from conventional conjugated polymers. Herein, we create the molecular super-hindrance-etching technology, based on the π-functional nanopolymer PG-Cz, to modulate multilayer cracks applied in organic single-component random lasers. Massive interface cracks are formed by promoting interchain disentanglement with the super-steric hindrance effect of π-interrupted main chains, and multilayer morphologies with photonic-crystal-like ordering are also generated simultaneously during the drop-casting method. Meanwhile, the enhancement of quantum yields on micrometer-thick films (
Φ
= 40% to 50%) ensures high-efficient and ultrastable deep-blue emission. Furthermore, a deep-blue random lasing is achieved with narrow linewidths ~0.08 nm and high-quality factors
Q
≈ 5,500 to 6,200. These findings will offer promising pathways of organic π-nanopolymers for the simplification of solution processes applied in lasing devices and wearable photonics.

Published: January 2023

Real stories always contain humanistic elements and it is appealing to ordinary people. Realism and short stories are the gift of nineteenth century. Realism is written in ordinary dialects and is based on ordinary human action, truth, degeneration and contradiction. Realistic stories are based on the life of ordinary people who is facing numerous problems. These stories are about the people who lost their unity, isolated away from family and caste. Contradictions among these people appears when they oppose the superstitious beliefs, norms and social sentiments. They act according to their nature and they never bow down to ordinary norms and practices. Vavesu Iyer’s “Kulathankarai Arasamaram” is a short story highlights the bankrupt of the British company which broke the dreams of countless middle-class people, the deterioration of the family life. This happened around 1910. Writer Puthumaipithan in his story “Ponakaram” tells ‘the world is different, dharmas are also different’. Indra Parthasarathy’s text “Kadhal Poar Viyabaram” depicts the rise of indiscipline among people during globalization. The text also implies that not all the people lost their moral values.

En los procesos de conducción en estado de ebriedad, se faculta a las partes para que lleguen al criterio de oportunidad, el mismo que tiene sus bases bien establecidas, que son la inmediatez, la celeridad, la concentración, entre otros. Por el estado de emergencia (debido a la COVID-19) cambiaron la forma y el modo de llevar a cabo las audiencias, y pasaron a realizarse de manera virtual, con lo cual se empezó a desnaturalizar el principio de inmediatez con respecto al pago de la indemnización civil, el mismo que antes se realizaba en el mismo acto. Así, es necesario ahondar en este punto que no solo afecta a la Corte Superior de Justicia de Huánuco, sino a todas las cortes del país, pues genera dilación innecesaria y más carga procesal, ya que el acuerdo nunca es realizado, y se le deja sin efecto y envía para un inicio de juicio oral.
Garantismo y razonamiento judicial

Los vestigios teóricos de las posturas paleo-positivistas han tenido como consecuencia directa una vehemente exaltación de la positivización de cualquier tipo de contenidos que se arguyan como derechos fundamentales, alegando con ello una adecuada regulación constitucional que, a la postre, sirve como discurso justificativo de la dominación estatal. Frente a esto, es importante analizar posturas teóricas como la garantista, que nos ayuden a comprender no solo cómo materializar los avances conseguidos en materia de protección a derechos fundamentales, sino también a reflexionar y criticar la actividad del sistema jurídico íntegramente, toda vez que su función ha sido notoriamente deslegitimadora del poder. Así, con este punto de partida epistémico, podremos dar cuenta de cómo la propia modificación de los distintos enunciados normativos y la función decisoria del juzgador se encuentran condicionados gracias a los contenidos sustantivos de las normas constitucionales.

Formal and technological attributes of pottery mirror potters’ habitus, actions, and decisions inhibited or stimulated by users of pottery. The variability of these attributes in time and space reflects networks of producers embedded in a complex social network. But how the knowledge of pottery manufacturing processes can be used to gain more accurate understanding of the society behind the “chaînes opératoires” when the basis for the interpretation is archaeological evidence? Can archaeologists reach reliable picture on relations between pottery technology and society? Can the interpretations be built on testable hypotheses? Those are painful issues accompanying all the archaeological attempts to understand variability and changes in pottery technology, the issues that motivate the main theme of the thematic issue of Archeologické rozhledy: the pursuit of archaeologists to integrate pottery technology analysis to the complex interpretation of the Neolithic societies.

Published: January 2023

Background: Chronic kidney disease combined with coronary artery disease is a growing public health issue. Preoperative renal dysfunction is one of the major risk factors for perioperative morbidity and mortality in patients undergoing coronary artery bypass grafting (CABG). This study aimed to analyze the early clinical outcomes of CABG in patients with preoperative renal impairment.

Methods: The study was conducted from July 2017 to July 2019. We included 100 patients who underwent CABG. Group A (n= 50) included patients with preoperative renal impairment and group B (n= 50) had patients with normal renal functions.

Results: The mean age was 63.3±9.1 years in Group A and 57.1±8.5 years in Group B (P<0.001). There were 35 males in Group A and 47 in Group B (P<0.001). Blood transfusion was more in Group A (47 (94%) vs. 32 (64%) patients; P=0.001). There was no difference in mortality between both groups.

Conclusion: Preoperative renal impairment in patients undergoing CABG is more common in elder females. Patients undergoing CABG with preoperative renal impairment could have a higher risk for blood transfusion.

Franciaországban Emmanuel Macron elnökségével visszatért a korábban leginkább Nicolas Sarkozy elnökhöz (2007–2012) köthető, nagy elánnal kezdeményező, erősen mediatizált és nem egyszer – főként a migránskérdés és a klímapolitika kapcsán – némileg álszent francia külpolitikai irányvonal, mely adott esetben a partnerek kritizálásában, kioktatásában is élen jár. Az alábbi elemzés először áttekinti a macroni Afrika-politika céljait és aktorait, majd a száhel-övezeti térség geopolitikájának és a terrorellenes küzdelem előzményeinek áttekintése után bemutatja a Barkhane, a Task Force Sabre és a Task Force Takuba műveletek főbb eredményeit, végül pedig az átszervezések részleteit.
wicked problem de la migración: narrativas y diseños de la política migratoria en Estados Unidos, 1990-2020
Authors: Villa Sánchez Sughei
Published: January 2023

Desde el análisis de políticas públicas, este trabajo explora el papel que juegan las narrativas sociales en la definición de un problema público altamente complejo (wicked problem), el de la migración en Estados Unidos. La forma en cómo se ha definido el problema de la migración en las últimas tres décadas en ese país, ha condicionado los procesos de formulación de la política migratoria, la cual ha adquirido tintes de sellamiento y securitización de la frontera México-Estados Unidos. Las narrativas que se han construido sobre los migrantes hispanos, criminalizándolos y haciendo de ellos la representación de sujetos peligrosos, han condicionado las respuestas gubernamentales de políticas de migración; a la vez que también se han construido narrativas deliberadamente, con la intención de legitimar socialmente un diseño dado de una política migratoria.

A Comprehensive Study on LPWANs With a Focus on the Potential of LoRa/LoRaWAN Systems
Authors: Milarokostas Christos , Tsolkas Dimitris , Passas Nikos , Merakos Lazaros
Published: January 2023

This publication offers a comprehensive survey on the topic of Low-Power Wide Area Networks (LPWANs). We discuss the scope of LPWAN connectivity and present numerous well-established technologies that can offer such a service. From this presentation, LoRa/LoRaWAN systems emerge as one of the dominant solutions, and hence we offer details about end-to-end LoRa/LoRaWAN-enabled networking. As an area being in its infancy, LPWANs in general and LoRa/LoRaWAN in specific undergo extensive research. We shed light in key contributions, whereas we also provide our findings regarding the main research focus and needs. Simulation studies appear to be a popular choice among researchers, whereas real system implementations are constantly emerging thanks to low deployment and operational cost. For the former, we offer a comparative overview of existing simulators, whereas for the latter we discuss key considerations about the server-side part of a deployed system, which is usually supported by cloud infrastructure. Finally, LPWANs are systems that experience intense data generation, and thus we deliver a presentation of data-related operations which take place in such systems. This presentation revealed a major vertical market that is expected to be served by LPWANs: the Industiral IoT; which embodies concepts like Asset Administration Shell and Digital Twins.
Design of a feedback restoring balanced compliant laparoscopic grasper
Authors: Klok Jan-Willem
Published: January 2023

Objective: In laparoscopic surgery, quality of haptic feedback is reduced compared to conventional surgery, leading to unintentional tissue damage during grasping. From the perspective of haptics, poor mechanical design of laparoscopic instrument joints induces friction and a nonlinear actuation -  tip force relation. In this study, a novel laparoscopic grasper using compliant joints and a magnetic balancer is presented, and the reduction in hysteresis and friction is evaluated. Methods & Results: The hysteresis loop of the novel compliant grasper and two conventional laparoscopic graspers (high quality Aesculap and low quality unbranded grasper) were measured. In order to assess quality of haptic feedback, the lowest grasper tip load perceivable by instrument users was measured with the novel and both the conventional laparoscopic graspers. The hysteresis loop measurement yielded a mechanical efficiency of 43% for the novel grasper, compared to- 25% and 23% for the Aesculap and the unbranded grasper, respectively. The forces perceivable by the user through the novel grasper were significantly lower (mean 1.37N, SD 0.44N) than those of conventional graspers (mean 2.15N, SD 0.71N and mean 2.65N, SD 1.20N, respectively). Conclusions: The balanced compliant grasper technology has the ability to improve the quality of haptic feedback compared to conventional laparoscopic graspers. Research is needed to relate these results to soft and delicate tissue grasping in a clinical setting, for which this instrument is intended. 
Optimized Residual Action for Interaction Control with Learned Environments

Robotic tasks featuring interaction with other bodies are increasingly required in industrial contexts. The manipulators need to interact with the environment in a compliant way to avoid damage, but, at the same time, are often required to accurately track a reference force. To this aim, interaction controllers are typically employed, but they either need human tinkering for parameter tuning or precise modeling of the environment the robot will interact with.

The former is a time-consuming procedure, while the latter is necessarily affected by approximations, which often lead to failure during the actual application. Both these aspects are problematic if it were often necessary to change the contact environment.Current research is concentrating on devising high-performance force controllers that are simple to tune and quick to adapt to changing environments.

Along this line, this work proposes a novel control strategy, that we term ORACLE (Optimized Residual Action for interaction Control with Learned Environments). It exploits an ensemble of neural networks to estimate the force generated by the robot-environment interaction. This estimate is input to an optimal residual action controller that locally corrects the main action, output of a base force controller, which guarantees stability.

The ORACLE strategy has been implemented and tested in the MuJoCo dynamic simulator and in a real-case scenario, both foreseeing a Franka Emika Panda robot used as a test platform. A reduction in terms of force tracking error is achieved by deploying the proposed strategy, with a short setup time.
Improving GEDI Footprint Geolocation using a High Resolution Digital Terrain Model

Published: January 2023

GEDI (Global Ecosystem Dynamics Investigation) is a lidar system on-board the International Space Station designed to study forest ecosystems. However, GEDI footprint low accuracy geolocation is a major impediment to the optimal benefit of the data. We thus proposed a geolocation correction method, GeoGEDI, only based on high-resolution digital terrain models (DTMs) and GEDI derived ground elevations. For each footprint, an error map between GEDI ground estimates and reference DTM was computed, and a flow accumulation algorithm was used to retrieve the optimal footprint position. GeoGEDI was tested on 150 000 footprints in Landes and Vosges, two French forests with various stands and topographic conditions. It was applied to GEDI versions 1 (v1) and 2 (v2), by either a single or four full-power laser beam tracks. GeoGEDI output accuracy was evaluated by analyzing shift distributions and comparing GEDI ground elevations and surface heights to reference data. GeoGEDI corrections were greater for v1 than for v2 and agreed with errors announced by NASA. Within forests, GeoGEDI improved the RMSE of ground elevation in Landes by 26.8 % (0.34 m) and by 13.3 % (0.14 m) for v1 and v2, respectively. For Vosges, ground elevation RMSE improved by 59.6 % (3.82 m) and 36.2 % (1.41 m), for v1 and v2, respectively. Regarding surface heights, except for v2 in Landes, where insufficient variations in topography combined to GEDI ground detection issues might have penalized the adjustment, GeoGEDI improved GEDI estimates. Using GeoGEDI showed efficient to improve positioning bias and precision.
Research on Optimization of Delivery and Pickup Vehicle Routing Problems Considering Cargo Loading
Authors: Pedro Manuel Julio
Published: January 2023

The VRP is a well-known combinatorial optimization problem in transport and logistics distribution. Customers require simultaneous pickup of goods from their location and the delivery of goods to their place in some cases. The cargo loading problem plays an essential role in physical distribution. The weight and volume of the vehicle are effectively used so that freight is reasonably loaded with as many goods as possible. A reasonable loading plan can improve the load and space utilization ratio of cars, reduce the logistics cost of distribution enterprises, and increase their competitive capacity. Therefore, the vehicle routing problem and cargo loading have gotten the great attention of logistics scholars and enterprises, and both belong to NP-hard problems. This paper presents a mathematical formulation and genetic algorithm method for solving a vehicle routing problem with simultaneous pickup and delivery and cargo loading (VRPSPD-CL), was analyzed the theory of logistics distribution optimization problem as a case study. The calculation example data was selected to analyze the actual problem of VRPSPD with cargo loading. The paper selected the genetic algorithm to solve the problem and improved GA and the basic genetic algorithm to get the optimal solution for the simulation experiment. Then, the paper concretely designs every step in the algorithm to make the algorithm compact, efficient, and fit, to solve the VRPSPD with cargo loading optimization and mathematical model was established. At the same time, MATLAB software is adopted to solve a related practical problem. Finally, the results obtained show the optimal objective function iteration value of the simulation experiment was satisfactory by the improved GA compare with the basic of GA for the VRPSPD cargo loading with the simulation.
