A U-shaped association between depression and vigorous physical activity: A cross-sectional study in a cohort of police officers and staff in England
Authors: Maqsood Rabeea , Buckingham Sarah , Morrissey Karyn
Published: June 2021

Policing has become an increasingly sedentary occupation. At the same time, rates of depression are increasing across the police force. Vigorous physical activity (VPA) has been associated with decreasing rates of depression, yet studies of VPA in policing are limited. This study aimed to explore the prevalence of depression and examine its association with VPA in police officers and staff in England, further stratified by gender. A cross-sectional, secondary data analysis of the Airwave dataset was undertaken. The data were analyzed using descriptive statistics and multivariate logistic regression. Of 28,465 police officers and staff in England, 12% reported having doctor-diagnosed depression and 25% were physically inactive. Relative to being physically inactive, undertaking VPA for either four or seven days was significantly associated with having the lowest odds of reporting depression (OR 0.59, 95% CI: 0.51–0.70, p < 0.001) (OR 0.59, 95% CI: 0.45–0.77, p < 0.001), respectively, suggesting a U-shaped/non-linear relationship. This relationship was also observed in the gender-stratification analysis. While the odds of reporting depression were significantly lower for men than women, VPA was significantly associated with reducing the odds of reporting depression slightly more in women (OR 0.43, 95% CI: 0.27–0.67, p < 0.001) than in men (OR 0.50, 95% CI: 0.33–0.75, p < 0.01), indicating women may be more likely to benefit from VPA than men. Vigorous physical activity may provide a protective effect against depression. To prevent the onset of depression in the target population, policy-makers should consider designing physical activity guidelines for police officers to promote VPA in the target population.

Published: June 2021

Seiring dengan kemajuan ilmu dan teknologi, modifikasi pada bentuk dan perhitungan daya dukung fondasi tiang pancang terus berkembang. Banyak ditemukan jenis ataupun bentuk-bentuk dari fondasi tiang pancang yang sudah dimodifikasi, salah satunya yaitu dengan penambahan sirip pada fondasi tiang polos. Tujuan penelitian ini untuk mengkaji perilaku daya dukung fondasi grup tiang sirip dengan variasi jumlah tiang pada tanah lunak, sehingga dapat diketahui perbandingan antara daya dukung fondasi grup tiang sirip dengan fondasi grup tiang polos serta  dapat diketahui perbandingan nilai efisiensi antara fondasi grup tiang sirip dengan tiang polos. Hasil analisis diperoleh perilaku daya dukung fondasi grup tiang sirip dengan variasi jumlah tiang 3T, 4T, 5T, 6T dan 8T memiliki kesamaan yaitu pada akhir kurva masih menunjukkan bahwa pada akhir penurunan masih terjadi peningkatan beban. Hal ini terjadi karena daya dukung friction dan end bearing yang dihasilkan fondasi, dengan keberadaan sirip meningkatkan  daya dukung end bearing fondasi. Sedangkan untuk model fondasi grup tiang polos menunjukkan daya dukung fondasi didominasi oleh friction. Daya dukung ultimate fondasi grup tiang sirip mempunyai daya dukung yang lebih besar dibandingkan dengan fondasi grup tiang polos. Peningkatan daya dukungnya  mencapai 28,88 % untuk variasi 3T, 53.11 % untuk variasi 4T, 36,18 % untuk 5T, 25,49 % untuk 6T dan 23,33 % untuk 8T. Fondasi grup tiang sirip dengan variasi jumlah tiang 8 memiliki daya dukung ultimate terbesar yaitu 108,1 N dan yang terkecil fondasi grup tiang polos dengan variasi jumlah tiang 3 yaitu 47,23 N. Berdasarkan hasil pengujian, efisiensi tertinggi ada pada fondasi tiang polos variasi 3T yaitu sebesar 3,15 dan terkecil 0,33 ada pada tiang sirip variasi 8T, hal ini dipengaruhi oleh peningkatan tekanan air pori di sekitar tiang akibat adanya penambahan sirip.
Towards Autonomous Estimation of Lightweight Object's Mass by a Humanoid Robot during a Precision Grip with Soft Tactile Sensors
Authors: Silva André
Published: June 2021

The estimation of the intrinsic properties of an unknown ob-
ject is a very challenging problem, mainly due the limitations on the
tactile technology. In this article we present a method to estimate an ob-
ject's weight during a precision grip made by a humanoid robot. Tactile
sensors on the ngertips provide information on the 3D force vector dur-
ing a movement of grasping and lifting a cup lled with dierent masses
(30-100g). Using the force measurements across time, we were able to
successfully calculate the object weight for 8 dierent masses in two sce-
narios: (i) Manually segmented force measurments and (ii) automatically
segmented force measurments. Regarding the manually segmented data,
we are able to have repeatable measurement and low deviations from the
real value, especially for higher object masses. Regarding the automat-
ically segmented data, we are able to identify the various phases of the
grasping experiment and use the segmented phases to compute the mass
automatically.
Packing Planning and Execution Considering Arrangement Rules
Authors: Yasuda Akiya , Alfonso Garcia Ricardez Gustavo , Takamatsu Jun , Ogasawara Tsukasa
Published: June 2021

To send a consumer the ordered products in e-commerce, it is necessary to pack the products into a container.
When packing, we need to consider the arrangement of the products to avoid damaging them during transportation by using the know-how of packing.
In this paper, we propose a packing robot system that plans the arrangement and then executes it.
To develop this robot system, we employ two ideas.
The first idea is to split the whole process into the arrangement of the objects and robot motion generation.
The arrangement is regarded as a 3D bin-packing problem.
The second idea is to use the heuristics of the packing so that objects are stacked from the bottom.
Since the space above the target position is free from collisions, the strategy to approach from the top reduces the possibility of a collision.
In the experiments, we succeeded in arranging eleven objects satisfying the assigned rules and packing ten of the eleven objects using the robot.
Reactive Navigation Framework for Mobile Robots by Heuristically Evaluated Pre-sampled Trajectories
Authors: Unver Akmandor Neset , Padir Taskın
Published: June 2021

This paper describes and analyzes a reactive navigation framework for mobile robots in unknown environments. The approach does not rely on a global map and only considers the local occupancy in its robot-centered 3D grid structure. The proposed algorithm enables fast navigation by heuristic evaluations of pre-sampled trajectories on-the-fly. At each cycle, these paths are evaluated by a weighted cost function, based on heuristic features such as closeness to the goal, previously selected trajectories, and nearby obstacles. This paper introduces a systematic method to calculate a feasible pose on the selected trajectory, before sending it to the controller for the motion execution. Defining the structures in the framework and providing the implementation details, the paper also explains how to adjust its offline and online parameters. To demonstrate the versatility and adaptability of the algorithm in unknown environments, physics-based simulations on various maps are presented. Benchmark tests show the superior performance of the proposed algorithm over its previous iteration and another state-of-art method. The open-source implementation of the algorithm and the benchmark data can be found at https://github.com/RIVeR-Lab/tentabot.
DQN as an alternative to Market-based approaches for Multi-Robot processing Task Allocation (MRpTA)
Authors: Gautier Paul , Laurent Johann
Published: June 2021

Multi-robot task allocation (MRTA) problems require that robots make complex choices based on their understanding of a dynamic and uncertain environment. As a distributed computing system, the Multi-Robot System (MRS) must handle and distribute processing tasks (MRpTA). Each robot must contribute to the overall efficiency of the system based solely on a limited knowledge of its environment. Market-based methods are a natural candidate to deal processing tasks over a MRS but recent and numerous developments in reinforcement learning and especially Deep Q-Networks (DQN) provide new opportunities to solve the problem. In this paper we propose a new DQN-based method so that robots can learn directly from experience, and compare it with Market-based approaches as well with centralized and purely local solutions.
Our study shows the relevancy of learning-based methods and also highlight research challenges to solve the processing load-balancing problem in MRS.
