Hybrid Sliding Mode Control of Full-Car Semi-Active Suspension Systems

With the advance in technology in driving vehicles, there is currently more emphasis on developing advanced control systems for better road handling stability and ride comfort. However, one of the challenging problems in the design and implementation of intelligent suspension systems is that there is currently no solution supporting the export of generic suspension models and control components for integration into embedded Electronic Control Units (ECUs). This significantly limits the usage of embedded suspension components in automotive production code software as it requires very high efforts in implementation, manual testing, and fulfilling coding requirements. This paper introduces a new dynamic model of full-car suspension system with semi-active suspension behavior and provides a hybrid sliding mode approach for control of full-car suspension dynamics such that the road handling stability and ride comfort characteristics are ensured. The semi-active suspension model and the hybrid sliding mode controller are implemented as Functional Mock-Up Units (FMUs) conforming to the Functional Mock-Up Interface for embedded systems (eFMI) and are calibrated with a set experimental tests using a 1/5 Soben-car test bench. The methods and prototype implementation proposed in this paper allow both model and controller re-usability and provide a generic way of integrating models and control software into embedded ECUs.

Double Feature

A Day in Hollywood/A Night in the Ukraine was a tiny jewel box of a musical revue, with a cast of just eight versatile performers, that established Tommy Tune as a director-choreographer of the first rank when it opened in 1980. Its second act was an adaptation of Anton Chekhov’s one-act The Bear as it might have been performed by the Marx Brothers. The trio’s cheerfully anarchic spirit was conjured with balletic grace and timing in Tune’s staging. Tune expanded the show’s curtain raiser, a series of Hollywood songs, into a satiric cavalcade of music and comic musings on the movies circa 1939, set in the lobby of Hollywood’s legendary Grauman’s Chinese Theatre and performed by its ushers. Its highlight was an ingenious tap number set to the text of the 1930 Hollywood Production Code, with all its taboos duly noted in rhythm.

A Duet for Sailors and Pansies: Queer Archival Work and Male Same-Sex Dancing in Follow the Fleet (1936) and Other Depression-Era Films

This chapter explores a queer all-male dance lesson for partnered sailors in the Fred Astaire–Ginger Rogers musical Follow the Fleet (1936), using archival research (scripts, Production Code Administration records) and comparative textual and contextual analysis. It raises the queerness of Rogers and Astaire before exploring two intersecting axes. The association of sailors with queer behavior and effeminate “pansies” occurs in military scandals, paintings, and Depression-era Hollywood films, including Sailor’s Luck and Son of a Sailor (both 1933). The queerness of male same-sex dancing arises in ballet and in film, including Suicide Fleet (1931). Various institutions criticized or attempted to censor such representations, but they also found acceptance. The US Navy, for example, wanted the comical dance lesson removed from Fleet; instead, it was only rewritten, suggesting the inability to remove queerness from culture and its essential role in mass entertainment.

Labelisasi Produk Pangan UMKM di Kecamatan Pulung Ponorogo

This research departs from labelling MSME food products that do not contain an expiration date, production code, and inclusion of a halal label without halal certification from MUI carried out by business actors in Pulung, Ponorogo. Based on this, this study aims to explain the sociological review of Islamic law on the practice of labelling MSME products in Pulung, Ponorogo, and a review of the sociology of Islamic law on the factors behind the labelling practice of MSME products carried out by business actors in Pulung Ponorogo District. The research method used is qualitative with data collection techniques through interviews and documentation. From this study, it can be concluded that the labelling practice carried out by business actors follows the three basic ideas of the symbolic interactionism theory proposed by Herbert Mead. This result is because every action taken by business actors is translated from the human mind (mind) about oneself (self) and carried out in the community (society) where the individual is located. The factors behind business actors doing labelling follow the three basic premises of the symbolic interactionism theory proposed by Blumer. Meanwhile, in the application of sharia economic principles, the actions of business actors are not following the principles of honesty and truth; some business actors are dishonest in providing information on labels.

Empirical Study of Test Case and Test Framework Presence in Public Projects on GitHub

Automated tests are often considered an indicator of project quality. In this paper, we performed a large analysis of 6.3 M public GitHub projects using Java as the primary programming language. We created an overview of tests occurrence in publicly available GitHub projects and the use of test frameworks in them. The results showed that 52% of the projects contain at least one test case. However, there is a large number of example tests that do not represent relevant production code testing. It was also found that there is only a poor correlation between the number of the word “test” in different parts of the project (e.g., file paths, file name, file content, etc.) and the number of test cases, creation date, date of the last commit, number of commits, or number of watchers. Testing framework analysis confirmed that JUnit is the most used testing framework with a 48% share. TestNG, considered the second most popular Java unit testing framework, occurred in only 3% of the projects.

Factor Analysis on Rice Product Labels as a Consideration for Consumer's Purchase Decision In Yogyakarta

Rice is one of the staple foods consumed by most Indonesians causes rice products to grow in line with consumer demand. As a widely consumed product, rice production labeling is a concern following the latest health issues. Labels are expected to provide useful information in determining products to be purchased by consumers, so it is necessary to know the information that consumers expect. This study aims to determine the attributes on the label that consumers consider when making purchasing decisions. The online questionnaire was filled in by 125 random respondents in Yogyakarta City and Sleman Regency, considering the current conditions (the Covid-19 pandemic). Determination of the factors taken into consideration using the Confirmatory Factor Analyze (CFA) method and appropriate statistical tools were used to analyze the data. The results showed that 74% of the respondents purchased labeled rice products in the last month. As many as 98.65% of respondents who bought labeled rice read the labels before making a purchase decision, and 78.38% considered labeling rice products important. Two factors are considered when making a purchasing decision: product specifications (price and production code) and product quality (organic labeling, net weight, nutritional content, BPOM registration number, and SNI label).

MENADŽMENT KONTROLE KVALITETA SOFTVERA UPOTREBOM BLACK-BOX TESTIRANJA NA POSTOJEĆEM WEBSHOP-U TRINITISHOP

Creating the need for continuous growth and progress of all involved and connected business entities. They require compliance with certain web standards and support for multiple different browsers and devices. To be convinced of the version of the published code, we need a team that loves challenges, has the creativity and a desire for constant learning. Code, as a basis for a successful business, must be written appropriately with minimal deficiencies in logic and writing. The correctness and validity of the production code mostly depend on the program team itself and its responsibility for the written code. Vital code with errors can produce serious problems and unforeseen consequences. To achieve complete accuracy of all parts of the written code, it is necessary to use software testing and QA technique - quality assurance. The focus of the work is on the application and writing of the necessary programming code that uses QA/QC and the black-box method of testing the existing webshop. After analysis, the authors conclude that software quality control will be a constant challenge for many companies to survive in the short term of the adjustment process and that the crisis is an opportunity for courageous companies to invest ambitiously and timely in their internet business to become market leaders.
