Quantum Period Finding against Symmetric Primitives in Practice

We present the first complete descriptions of quantum circuits for the offline Simon’s algorithm, and estimate their cost to attack the MAC Chaskey, the block cipher PRINCE and the NIST lightweight finalist AEAD scheme Elephant. These attacks require a reasonable amount of qubits, comparable to the number of qubits required to break RSA-2048. They are faster than other collision algorithms, and the attacks against PRINCE and Chaskey are the most efficient known to date. As Elephant has a key smaller than its state size, the algorithm is less efficient and its cost ends up very close to or above the cost of exhaustive search.We also propose an optimized quantum circuit for boolean linear algebra as well as complete reversible implementations of PRINCE, Chaskey, spongent and Keccak which are of independent interest for quantum cryptanalysis. We stress that our attacks could be applied in the future against today’s communications, and recommend caution when choosing symmetric constructions for cases where long-term security is expected.

Analysis of the Effectiveness and Study on Long-Term Mechanism of Sports World Campus App in Monitoring Extracurricular Physical Exercise of College Students

The data of extracurricular physical exercise of college students before, at the time of, and after being monitored were compared and analyzed by the Sports World Campus app (a running app), and it was concluded as follows: (1) compared with the data before being monitored, the average number of running times per week and the proportion of physical education population increased significantly during and after being monitored; (2) compared with the data at the time of being monitored, the average number of running times per week and the proportion of physical education population decreased significantly after being monitored; and (3) per academic year, the average number of running times per week and the time of running increased year by year in the three years of being monitored. To derive a long-term mechanism, it is necessary to (1) raise the attention of school authorities, strengthen the supervision in management, and formulate a reasonable reward and punishment system; (2) optimize the quality of running apps to improve students’ sense of running experience; (3) set a reasonable amount of tasks per semester to guide students to conduct extracurricular physical exercise scientifically; and (4) promote students’ overall development, establish a culture of extracurricular physical activities, and cultivate students’ lifelong sports awareness.

Optimized Control of Virtual Coupling at Junctions: A Cooperative Game-Based Approach

Recently, virtual coupling has aroused increasing interest in regard to achieving flexible and on-demand train operations. However, one of the main challenges in increasing the throughput of a train network is to couple trains quickly at junctions. Pre-programmed train operation strategies cause trains to decelerate or stop at junctions. Such strategies can reduce the coupling efficiency or even cause trains to fail to reach coupled status. To fill this critical gap, this paper proposes a cooperative game model to represent train coupling at junctions and adopts the Shapley theorem to solve the formulated game. Due to the discrete and high-dimensional characteristics of the model, the optimal solution method is non-convex and is difficult to solve in a reasonable amount of time. To find optimal operation strategies for large-scale models in a reasonable amount of time, we propose an improved particle swarm optimization algorithm by introducing self-adaptive parameters and a mutation method. This paper compares the strategy for train coupling at junctions generated by the proposed method with two naive strategies and unimproved particle swarm optimization. The results show that the operation time was reduced by using the proposed cooperative game-based optimization approach.

Design and Simulation of a 2KVA Inverter with an Overload Protector

In this research, the design and simulation of 2000VA inverter is presented. The method implemented for the design was the d.c. – a.c. inverter topologies. The d.c. – a.c. inverter circuit made use of a 555 timer, to digitally pulse the transistors on the inverter side, and the oscillating circuit, to drive the inverter. The system consists of the main inverter stage and the charging unit. These units are further subdivided into different stages. The main inverter performs the basic operation of converting the input d.c. voltage from the battery into an a.c voltage. The charging unit contains an automatic switch that charges the battery when it senses no supply from the mains. Each unit of the project was simulated individually at every different stage of the design by using a simulating software (every circuit). The waveform given at the final stage of the simulation shows that it is a modified sine wave inverter, and it successfully converts a 12V d.c. into a 220V a.c. with a load capacity of 2000VA. The inverter should be able to power the electronic device connected for a reasonable amount of hours

The Canadian Occupational Performance Measure: A Feasible Multidisciplinary Outcome Measure for Pediatric Telerehabilitation

This study describes the feasibility of using the Canadian Occupational Performance Measure (COPM) as a multidisciplinaryoutcome measure for pediatric telerehabilitation (TR). The COPM was administered at monthly time points over four months. A follow-up survey was conducted with the therapists to assess clinical utility of the COPM. Seventy-three percent of the children seen in TR > one month had at least two administrations of the COPM. Eighty percent of therapists agreed or strongly agreed that the COPM was easy to use in a reasonable amount of time, helped identify functional goals, could be used with various children with varied diagnoses, and measured functional change. In 37 children, the median clinical change in performance and satisfaction was two points or greater on the COPM over the episode of TR. The COPM is a feasible measure perceived positively by pediatric therapists for TR use.

Multi-robot informative path planning in unknown environments through continuous region partitioning

We consider the NP-hard problem of multirobot informative path planning in the presence of communication constraints, where the objective is to collect higher amounts of information of an ambient phenomenon. We propose a novel approach that uses continuous region partitioning into Voronoi components to efficiently divide an initially unknown environment among the robots based on newly discovered obstacles enabling improved load balancing between robots. Simulation results show that our proposed approach is successful in reducing the initial imbalance of the robots’ allocated free regions while ensuring close-to-reality spatial modeling within a reasonable amount of time.

A REVIEW ON THE STANDARD OPERATIVE PROCEDURE OF NASYA

Ayurveda is the science, which deals with the maintenance of health and treats the disease. Rasayana Aushadhi, Pathya-Apathya, Dinacharya, Rutucharya etc are explained in Samhitas for maintaining the health. Nasya is one of the Panchakarma used for eradication of Urdhvajatrugat Dosha (disease of head and neck). Although Nasya is included in Shodhan Chikitsta, it has various other uses as Shaman for health maintenance and controlling the disease. Today’s lifestyle is very fast growing and having lack of time to look for their health issues. Nasya is the most preferred procedure as it consumes a very reasonable amount of time and can be performed easily as compared to other Panchakarma therapies like Vaman, Virechan and Basti. There is a need to have standard operative procedure, as its effect is largely dependent on the proper administration of Nasya. If this procedure is not followed properly and according to the classics, then there are chances of Vyapad (complications). This article will focus on the standardization of Nasya Karma procedure, Nasya Kal (timing at which Nasya is to be administered) and its importance in today’s lifestyle.

Intelligent Buses in a Loop Service: Emergence of No-Boarding and Holding Strategies

We study how N intelligent buses serving a loop of M bus stops learn a no-boarding strategy and a holding strategy by reinforcement learning. The no-boarding and holding strategies emerge from the actions of stay or leave when a bus is at a bus stop and everyone who wishes to alight has done so. A reward that encourages the buses to strive towards a staggered phase difference amongst them whilst picking up passengers allows the reinforcement learning process to converge to an optimal Q-table within a reasonable amount of simulation time. It is remarkable that this emergent behaviour of intelligent buses turns out to minimise the average waiting time of commuters, in various setups where buses move with the same speed or different speeds, during busy as well as lull periods. Cooperative actions are also observed, e.g., the buses learn to unbunch.

Capacity Building in Cooperative Organization: Ground for Change

The concept of capacity building in cooperative society exist in all aspect of cooperatives activities and it is the important strategy that enable cooperative society and its members to perform effectively well in line with their goal and cooperative principles. For any cooperative society to perform very well and be able to compete favorably, it must invest reasonable amount of money to develop the ability of its members, employees and the society itself.
