RELASI AKTOR DALAM IMPLEMENTASI KEBIJAKAN PENDIDIKAN MENENGAH DI KOTA MATARAM
Authors: Ali Muhammad
Published: June 2021

Abstract, Secondary education policy needs to be improved by a process which is a strategic alternative to improve the quality of education. This paper examines the relation of actors in the implementation of secondary education policy in the city of Mataram which focuses on senior secondary education as an education sub-system by formulating and implementing education-related policies that are trademarks for the achievement of policy objectives. The Key to Policy Implementation uses a participatory approach in public policy making in education supported by 4 (four) factors as a driver of successful policy implementation. But in reality there are causes of the implementation of policies that have not optimally reached their objectives, namely: a). Communication b). Resources (Resources), c). Implementor Attitudes (Dispositions), and d). Bureaucratic Structure (Bureaucratic Structure). Then, on the other hand, the Government's relation with actors outside the government is not yet optimal, where the government has not effectively built relationships with the community and the business world so that governance has not been created in the implementation of secondary education policies. This condition requires improvement of aspects of policy implementation and improvement of coordination between actors and organizational culture towards the achievement of secondary education policy objectives in supporting governance in the city of Mataram. Keywords: Policy Implementation, Secondary Education, Governance  Abstrak, Kebijakan pendidikan menengah perlu ditingkatkan dengan suatu proses yang merupakan alternatif strategis untuk meningkatkan kualitas pendidikan. Tulisan ini mengkaji relasi aktor dalam implementasi kebijakan pendidikan menengah di kota mataram yang menitikberatkan pada pendidikan menengah atas sebagai sub sistem pendidikan dengan merumuskan dan melaksanakan kebijakan terkait pendidikan yang menjadi trademark unttuk tercapainya tujuan kebijakan. Kunci Implementasi kebijakan menggunakan pendekatan partisipatory dalam pengambilan  kebijakan publik  bidang pendidikan yang ditopang oleh 4 (empat) faktor sebagai pendorong  keberhasilan implementasi kebijakan. Namun secara realitas adanya penyebab implementasi kebijakan yang belum secara optimal mencapai tujuannya yaitu: a). Komunikasi b). Sumber Daya (Resources), c). Sikap Implementor (Dispositions), dan d). Struktur Birokrasi (Bureaucratic Structure). Kemudian pada sisi yang lain relasai Pemerintah dengan aktor di luar pemerintah yang belum optimal, dimana pemerintah belum secara efektif membangun relasi dengan masyarakat dan dunia usaha sehingga belum tercipta governance dalam implementasi kebijakan pendidikan menengah. Kondisi ini memerlukan pembenahan terhadap aspek-aspek implementasi kebijakan dan peningkatan koordinasi antar aktor  dan budaya organisasi ke arah pencapaian tujuan kebijakan pendidikan menengah dalam mendukung governance di kota Mataram. Kata Kunci: Implementasi Kebijakan, Pendidikan Menengah, Governance
Incomplete crime as an object of humanization of the Russian criminal legislation
Authors: Lapshin V. F. , Kilimbaev R. V.
Published: June 2021

The subject. The article is devoted to the problems of simultaneous harmonization between the policy of humanization of the Russian criminal law and the reduction of the crime rate in society. The institute of incomplete crime is proposed as one of the promising areas of humanization of criminal legislation. The authors analyze the norms of the Russian Criminal Code which determine the essence of an incomplete crime, as well as the specifics of imposing punishment for its commission. The subject of the research also includes the strategic provisions of the Russian legislation, which reflect the main directions of the implementation of contemporary criminal policy, its goal and objectives. The purpose of the article is to confirm or dispute hypothesis that it is inadmissible to criminalize the actions committed at the stage of preparation for the commission of an intentional crime, as well as it is admissible to mitigate the liability for attempted crime. Research methodology and techniques are represented by a number of general scientific and specific scientific methods of cognition, used primarily in humanitarian research. The establishment of regularities between the growth of crime rates and the degree of criminalization, determined in the current criminal legislation, is ensured by the use of the dialectical method of cognition. The methods of analysis and synthesis were used to compare statistical data on the state of crime in Russia and the dynamics of the number of convicts serving imprisonment. Various methods of formal logic were applied in the process of evaluating measures aimed at ensuring the humanization of modern Russian criminal legislation. The method of comparative legal research was used to study the content of the norms on responsibility for an incomplete crime. The result of the study is proof of the necessity to decriminalize actions that are currently defined as "preparation for the commission of a grave or especially grave crime." The necessity of a significant reduction in the degree of punitive criminal-legal impact on persons found guilty of an attempt to commit an intentional crime has been substantiated. Conclusions. It as expedient to partially decriminalize an incomplete crime and exclude this institution from the General Part of the Russian Criminal Code. This decision fully complies with the fundamental principles of criminal law: legality, guilt, justice, and will also ensure the effectiveness of the implementation of the modern policy of humanizing Russian criminal legislation.

Published: June 2021

The relevance of the study of the problem of blended learning and the motivational component is conditioned by its increasing publicity among modern scientists and teachers. The purpose of this study is to reflect the scenario of modern educational trends, namely the gradual transition to a hybrid learning format, which is inevitable for modern society. Theoretical, empirical, and comparative research methods were used to study the problem of motivation of students and teachers in the application of blended learning. These methods helped to deeply explore the subject matter, to identify and analyse the individual elements of the problem and to understand the main idea of the object under study. Blended learning has been found to be a new educational approach that combines the advantages of the conventional system of knowledge acquisition and e-learning. It is demonstrated that such training is considered an effective approach and is popular among educational institutions due to its positive impact on student motivation. It is substantiated that the hybrid form helps teachers to involve students in learning and promotes the development of social and practical skills. It is confirmed that with the development of blended learning, students feel more confident and motivated, and teachers develop professionally and become good professionals. Technology has simplified young people's lives and brought teachers closer to students. It is proved that with the development of blended learning it is possible to obtain materials with relevant information, practice of the so-called hard skills is carried out using modern technology, new versions of educational software. Thus, the study reproduced the problem of blended learning as such, and argued the need for a detailed consideration of any scientific problem, considering all its primary factors and further consequences

The purpose of this study was to investigate the relationship between the alveolar bone and gingival dimensions in the maxillary anterior teeth. Cone-beam computed tomography images of 160 maxillary anterior teeth were evaluated. The Bone (BT) and Gingival Thickness (GT) and distances between Cemento-Enamel Junction (CEJ) and alveolar Bone Crest (CEJ-BC) and Cemento-Enamel Junction and Gingival Margin (CEJ-GM) were measured on the labial surface at the cervical third of the tooth root. Pearson correlation test or partial correlation was used. BT was significantly and positively associated with CEJ-GM in lateral incisors (p=0.04). The correlation between CEJBC and CEJ-GM was negative and statistically significant for incisors and canines (p≤0.01). The correlation between CEJ-BC and GT was positive and statistically significant for central incisors and canines (p≤0.01). Greater bone thickness was associated with higher gingival margin level at the lateral incisor, but not with bone crest level. Lower bone crest level was associated with greater gingival thickness at the central incisor and canines, and with lower gingival margin level at all the anterior maxillary teeth. The planning of orthodontic, periodontal, and restorative treatments should consider these dimensions of marginal periodontal tissue are interrelated and their relationship vary by tooth type.

Exchange Rates and Dominant Macro Fundamental
Authors: Gholampour Vahid
Published: June 2021

Various exchange rates are driven by different macro variables. This paper uses a measure of exchange rate informativeness about future macro fundamentals to identify the dominant macroeconomic fundamental of 120 currencies. Exchange rate informativeness is defined as the share of future fundamental shocks in the variance of exchange rate changes. The distribution of exchange rate informativeness shows that the median exchange rate informativeness about the dominant macro fundamental is 0.11. Moreover, the exchange rate of most high-inflation countries is driven by expectations of the price differential. Expectations of the relative output drive the currency of countries with high export concentration.

Los conceptos en la resolución de problemas de física "bien estructurados": aspectos identificativos y aspectos formales
Authors: Carcavilla A. , Escudero Escorza Tomás
Published: June 2021

Este trabajo trata de analizar la resolución de problemas cerrados de física general del tipo de los que se proponen habitualmente en los libros de texto. Consideramos que, al resolver uno de esos problemas, se debe construir una representación del mismo y para ello deben realizarse una serie de tareas que se pueden dividir en dos tipos: de identificación y de competencia lógica. Se han analizado los errores en ambos y se ha concluido que una de las principales causas de los errores en la resolución de este tipo de problemas es la falta de significado más que el uso de un significado propio del resolvente. En la fundamentación teórica se han utilizado ideas de procedencias muy diversas: de Neimark, de Van Dijk y Kintsch y de Eco, entre otros.

Enseñanza de las ciencias y filosofía
Authors: Paruelo Jorge
Published: June 2021

La epistemología es una de las herramientas necesarias para el desarrollo de nuevas estrategias para la enseñanza de las ciencias. Sin embargo, no está claro el rol que esta disciplina juega en este proceso. En este trabajo presento una serie de ejemplos extraídos de manuales de uso habitual en la enseñanza de las ciencias donde se detecta la falta de un correcto análisis epistemológico. Identifico dos roles para los filósofos de la ciencia: la tarea de formación epistemológica de los docentes de ciencia y la investigación acerca de los costos epistemológicos de la transposición didáctica y de los supuestos que tiene la ciencia enseñada.
Conocimientos que interaccionan en la enseñanza de las ciencias
Authors: Marín Martínez Nicolás
Published: June 2021

En la enseñanza de las ciencias confluyen una diversidad de conocimientos: cotidiano, de ciencias, del alumno, académico o del profesor. Ante esto, cuando se fundamenta cualquier propuesta para enseñar ciencias se dan dos tendencias básicas según se enfaticen las analogías o las diferencias de los conocimientos citados. Este trabajo viene a sumarse a los que esgrimen las diferencias entre el conocimiento de ciencias y el del alumno para revisar propuestas didácticas que se basan en la analogía del «alumno como científico».
La planificación de las actividades de los estudiantes en los trabajos prácticos de física : análisis de prácticas de profesores
Authors: Richoux Hélène , Beaufils Daniel
Published: June 2021

Los trabajos prácticos ocupan un lugar importante en la enseñanza de la física y de la química y son generalmente presentados como el lugar de realización de actividades científicas. Este artículo es un estudio de la elaboración de trabajos prácticos por parte de profesores de secundaria, realizado sobre la base de entrevistas y de observaciones de clases. Un primer análisis muestra que los profesores no hacen en realidad ninguna referencia a la actividad científica y que la planificación de la sesión recibe la máxima atención. La elaboración de una parrilla específica ha permitido un análisis detallado que muestra una coherencia fuerte entre planificación y «razones» invocadas por los profesores. Proponemos como síntesis un modelo de funcionamiento del «profesor-constructor».

La "distancia" entre aprender palabras y aprehender conceptos. El entramado de palabras-concepto (EPC) como un nuevo instrumento para la investigación
Authors: Galagovsky Lydia R. , Muñoz Juan Carlos
Published: June 2021

El análisis de los contenidos tratados en la clase, mediante los cuales el discurso científico se transpone en discurso escolar, es uno de los campos de investigación educativa menos explorados.En el presente trabajo definimos un nuevo instrumento, que hemos denominado entramado de palabras concepto (EPC), que permite la transformación de un documento de formato texto, en otro de formato gráfico-semántico. Este nuevo instrumento puede aplicarse para analizar textos discursivo-comunicativos, tales como la carpeta de algún alumno, los apuntes del propio profesor, etc., abriendo la perspectiva de realizar investigaciones tanto sobre el tratamiento del discurso en una clase dada como para estudios transversales a partir del análisis de carpetas de alumnos de diferentes años, de diferentes profesores, de diferentes regiones, etc.En este trabajo se mostrará la construcción y aplicación de un EPC obtenido a partir de la carpeta de un alumno, para el tema «Energía», desplegado en unas clases de física de tercer año de escuela secundaria.
Estudio de la diversidad de interpretaciones de la norma matemática en un aula multicultural
Authors: Planas Raig Núria , Gorgorió Solà Núria
Published: June 2021

This paper is included in a qualitative research carried out in a classroom with 15-16 year-old minority and economically disadvantaged students. The research tries to develop an inclusive approach for integrating both the cognitive and emotional perspective in order to improve the comprehension of the processes of constructing meanings in the classroom microculture. We assume that multicultural classrooms promote more evidence about the variety of meanings and values concerning with the mathematical practice. It is our intention to think over the possible interferences in learning that can be derived from the different interpretations of mathematical norms in the classroom. The results of our analyses should be a contribution for a better understanding of this phenomenon.

Published: June 2021

The objective of this article is to undertake a deep analysis of the pedagogical aspects related to the teacher’s dialogical ability under teaching conditions. The work begins with a study of the outline, content and meaning of activities that are considered to be able to stimulate an effective dialogue with students, according to opinions expressed by teachers. The contextualized results were then analysed and interpreted on the basis of contributions from a psychoanalytical reference frame. Although these considerations undoubtedly contain a strong theoretical option, our perspective may work as a stimulus for other didactic alternatives and also for a reanalysis of previous research.
Educational activities of the Road Transport Inspection
Authors: Raźny Bartosz , Domagała Kamil
Published: June 2021

The aim of this article is to describe educational activities concerning improvement of road safety taken by the [Polish] Road Transport Inspection. In order to build awareness of our society some actions should be taken at the earliest age and involve many different institutions, not only schools. The authors show how the Road Transport Inspection fulfils this assumption by creating “Bezpieczna Szkoła Krokodylka Tirka” (‘Crocodile Tirek's School of Safety’), organising lessons about road safety in hospitals, high schools or lectures on conferences, fairs and other events concerning transportation, logistics and shipping. The Engagement of the Road Transport Inspection in education and media campaigns involving road safety has been discussed in the range of years 2018-2020 and it shows the dynamic development of the unit on this field. Our analysis indicates that the most effective in education is combination of both theory and practise or sharing by officers, their knowledge and work experience with the audience. The biggest challenge, on the contrary, is to bring all this activities to the Internet, which is necessary especially because of coronavirus pandemic.
The influence of iron availability on the structural changes of skeletal muscle cells and cardiac muscle cells
Authors: Kobak Kamil A.
Published: June 2021

In the presented study, the influence iron availability on the cell morphology and structure was examined in skeletal myocytes cultured under normoxic and hypoxic conditions. The study showed that iron deficiency in vitro (especially in combination with hypoxia) has a detrimental effect on skeletal myocytes. Cellular disfunction was manifested by atrophic changes in cell morphology, structural remodeling of cells and increased expression of muscle atrophy markers. Interestingly, increased iron availability appeared to have some protective properties in the context of aforementioned changes. Moreover, based on clinical data and recent transgenic models, structural and functional abnormalities in iron-deficient cardiac muscle were described and the potential pathomechanisms behind them have been discussed.
The issue of dactyloscopy in terms of police activities
Authors: Druszcz Julia , Liberacki Marcin
Published: June 2021

Fingerprints have been known since the dawn of time and as early as in the Stone
Age they were used to sign agreements and deeds. Dactyloscopy – a field of criminology
– arose and developed thanks to technological progress. Fingerprints accompany
human beings throughout their entire lives, from their early beginnings in their mothers’
wombs to their death. They cannot be changed or removed without damaging the dermis
of fingers. Lines which can be observed on the fingertips make systematic patterns.
People leave dactyloscopic traces on a daily basis. It is the consequence of a special
reaction of the substance which includes both sweat and fat. This substance comes
off the fingertip and leaves traces.
Fingerprints traces can be disclosed with the use of different methods. The spectrum
of these methods is very wide. It was reflected and indicated in the content of this publication. Procedures play a very important role in the work of dactyloscopy technicians.
They have an incredible impact on the success of the entire process of people’s
identification with the use of fingerprints which were left. Implementation of established
algorithms is crucial with regard to the possibility to collecting all the evidentiary
material effectively.
Identification and comparison of fingerprints traces constitute very important elements
in the work of law enforcement authorities. Automated Fingerprint Identification
System (AFIS) facilitates this processing. AFIS is in the possession of a huge database
allowing for an identification of fingerprints in a shorter time. Without that tool, it would
be difficult or even impossible to compare different fingerprints.
The authors show the development of methods, techniques and research instruments
which are used in the identification process. The development of modern technologies
combined with achievements in biology or chemistry will cause further, perpetual
evolution in the researched field.
A substantive administrative matter in an abstract perspective versus a substantive administrative matter in a concrete sense
Authors: Szremski Jakub
Published: June 2021

The admissibility of the administrative procedure in question is related to the necessity
of an individual administrative case. It is the subject of an ongoing administrative
process. Its boundaries define the “area” of jurisdictional activity of the adjudicating
body. Thus, the determination of the scope of an individual administrative case will
constitute the limits of the conducted process. The legislator does not define the term
“administrative matter”. The scope of this concept includes an abstract substantive
administrative case (existing before the formal initiation of proceedings) and a specific
substantive administrative case (existing as part of an ongoing administrative procedure).

Background: The aim of this study was to evaluate the effect of cardiac rehabilitation on electrocardiographic changes in patients undergoing isolated coronary artery bypass grafting.

Methods: Between January 2016 and July 2019, a total of 625 patients (485 males, 140 females; mean age: 59.6 years; range, 50.6 to 68.6 years) who underwent isolated coronary artery bypass grafting and survived were retrospectively analyzed. The patients were divided into two groups according to the participation in the cardiac rehabilitation program as follows: the Rehab(+) group (n=363) and the Rehab(-) group (n=262). Electrocardiographic parameters of both groups were compared.

Results: There was a significant decrease in the electrocardiographic findings of heart rate (p<0.001), QTc (p<0.001), Tpe duration (p<0.001), Tpe/QT ratio (p<0.001), and Tpe/QTc ratio (p<0.001) in the Rehab(+) group before and after surgery. There was a significant decrease in the Rehab(+) group, compared to the Rehab(-) group, in terms of parameters of QT interval (p=0.001), QTc (p=0.017), Tpe duration (p<0.001), Tpe/QT ratio (p<0.001), and Tpe/QTc ratio (p<0.001).

Conclusion: Cardiac rehabilitation program after coronary artery bypass grafting decreases ventricular repolarization indices of electrocardiography. Based on these changes, postoperative cardiac rehabilitation program may reduce the risk of ventricular arrhythmia and sudden cardiac death during follow-up.
Management of Takotsubo cardiomyopathy before non-cardiac surgery: A case report
Authors: Gürol Tayfun
Published: June 2021

Takotsubo cardiomyopathy (left ventricular apical balloon syndrome) is characterized by transient apical ballooning, leading to apical systolic dysfunction. This syndrome typically mimics acute coronary syndrome in terms of electrocardiographic changes and cardiac enzyme release. Although its exact pathophysiology is still unclear, it is thought to be due to stress related to the catecholaminergic discharge. It is usually seen on postmenopausal women. Herein, we report a 78-year-old female patient with Takotsubo cardiomyopathy admitted to the orthopedic surgery clinic due to a femoral fracture and had no complication after surgery.

Daktilitas struktur merupakan syarat yang harus dipenuhi pada struktur tahan gempa dimana struktur mampu berdeformasi besar pasca leleh tanpa runtuh. Kondisi demikian hanya dapat terjadi jika struktur direncanakan mengikuti kaidah strong column weak beam dimana ketika terjadi gempa kuat sendi plastis hanya boleh terjadi pada balok di muka kolom kecuali pada kolom lantai dasar. Dengan demikian maka balok harus mempunyai daktilitas yang cukup agar dapat berotasi besar tanpa ada penurunan kapasitas secara signifikan. Penelitian ini merupakan bentuk inovasi baru dalam peningkatan daktilitas penampang beton bertulang. Dua tipe benda uji masing-masing dengan rasio pembesian r=0.0095 dan r=0.0190, yang merepresentasikan tingkat kepadatan tulangan meskipun masih dalam kondisi under-reinforced. Balok dengan initial N dan P masing-masing merupakan balok kontrol dan balok dengan penambahan pelat baja dengan lebar 500 mm dan tinggi 5 mm pada permukaan beton tekan. Penambahan pelat baja pada masing-masing tipe menunjukkan selain peningkatan pada kapasitas dan kekakuan, juga peningkatan daktilitas yang sangat signifikan, dimana pada balok dengan r=0.0095 pengaruhnya lebih besar dibanding balok dengan r=0.0190.

Penelitian ini bertujuan menentukan tarif optimal Kereta Bandara Soekarno Hatta dengan fungsi permintaan yang diturunkan dengan pendekatan discrete-choice experiment. Fungsi permintaan diperoleh dengan memprediksi pilihan setiap individu pada beberapa tingkat harga yang berbeda, mengagregasikannya, dan kemudian menginterpolasikannya sehingga diperoleh fungsi yang kontinyu dan differentiable. Pilihan setiap individu diprediksi dari data utilitas individual menggunakan simulasi randomized first choice, sementara interpolasi fungsi permintaan dilakukan menggunakan cubic spline. Utilitas individual diestimasi dari data stated-preference berbentuk choice menggunakan pendekatan Bayesian. Dengan membatasi dua kelas tarif, harga ditentukan dengan mempertimbangkan kanibalisasi antar kelas tarif dan memperhatikan profitabilitas jangka panjang. Formulasi masalah optimasi yang diperoleh berbentuk nonlinear integer programming dengan fungsi tujuan polinomial orde empat yang parameternya dipengaruhi oleh nilai variabel keputusan. Ruang solusi yang tidak terlalu luas memungkinkan untuk memperoleh solusi dengan enumerasi, di mana diperoleh tarif optimal sebesar Rp67.000 untuk kelas tarif 1 di mana layanan Kereta Bandara dibundle dengan diskon angkutan taksi berbasis aplikasi, dan Rp57.000 untuk kelas tarif 2 yang berupa layanan Kereta Bandara saja. Dengan tarif tersebut diperkirakan akan diperoleh kontribusi total sebesar Rp274,68 milyar per tahun.
DIRIGISMO JUDICIAL NOS CONTRATOS EDUCACIONAIS: LIMITES E CRITÉRIOS À INTERVENÇÃO ESTATAL NO PREÇO DAS MENSALIDADES ESCOLARES.

Since the normativeorganization supported by an analytical Federal Constitution, containing general and abstract norms that claim the judges to active participationin the realization of justice, in specifics cases, has been opened space for judicial activism. In the theoryof the contracts, the formulations of new paradigms, such as equity, good faith and social function authorizes the state intervention in privatesbusiness. Especially in the adhesion contracts, in consumer relationships. State intervention, however, have to respect constitutional principles, such warranty of free enterprise, and private property. This article, therefor, through the deductive method, aims to contribute to the considerations ofthe possibility of states intervention in privateeducationalcontracts, reconciling the capitalist model adoptedin Federal Constitution order and the guarantees inherent to with the protection of consumers, without this implying as affront to the Federal Constitutionlimits.To this is necessary to apply the techniqueof weighing constitutionalrights in conflict. The article suggests that State should not intervene in setting private prices, but to facilitatepayments.
Experiment and Smooth Particle Hydrodynamics Simulation for the Wear Characteristics of Single Diamond Grit Scratching on Sapphire
Authors: Wu Haiyong
Published: June 2021

Abrasive single crystal diamond (SCD) grit is widely used in the machining process of sapphire. The wear of SCD grit has a significant influence on the surface quality of sapphire. In this paper, smooth particle hydrodynamics (SPH) method is employed to reveal the wear mechanism of SCD grit with Steinberg constitutive equation and Grüneisen state equation. The wear morphology, wear volume and scratching forces are measured and analyzed by combination of SPH simulations and experiments. The results show that the scratching forces fluctuate in a certain range and decrease with the increasing of workpiece material removal volume. Different degrees of cleavage and fracture appear in the front and rear of SCD grit. The shear stress and extrusion stress are the main stresses of SCD grit during the scratching process. The wear progress and wear form are mainly determined by the stress state. Different stress state leads to different wear progress of the SCD grit. The SPH method is able to reflect and illustrate the wear characteristics of SCD grit scratching on sapphire.
Simulation Study of Balancing Arm Arrangement for Controlling Base Disturbances in Long Reach Manipulators
Authors: SRINIVASAN A. , JEGAN A.
Published: June 2021

The dynamics of the Long Reach Manipulators create disturbances in its supporting base structure. This causes positional and attitude inaccuracies of the end-effector, thwarting the accomplishment of the desired mission task. Hence the base disturbance problem has been a subject of research since long time bringing solutions from varied domains. This paper analyzes the balance link concept for compensating the disturbances. The LRM system is modelled as a two-link serial chain with payload, and the balance arm, as a single link with tip mass that is dynamically varied by controlling the quantity of the hydraulic fluid in the bellows-like reservoir at the tip. The supporting base is modelled as a half car. Simultaneous constraint matrices are set up for the arrangement, and dynamic simulation is performed using SIMULINK. The pitch and bounce motions of the base are studied along with the torque error during compensation. The simulation plots are obtained for two conditions of compensating arm¾with fixed tip mass and with varying tip mass. The results confirm the suitability of the suggested compensating arrangement in controlling base disturbances.
