A multidisciplinary system identification of the human precision grip
This thesis focus on the unique human ability to pick up and manipulate small objects using the precision grip, i.e., the fine grip between the index finger and the thumb. This ability is formed by the interplay between the complex biomechanical machinery of the hand and the neural networks within the central nervous system. To gain further knowledge about how humans control the precision grip, both the biomechanical system and the neural control system has to be examined.For the control system, we used functional magnetic resonance imaging on human subjects to mapout the cortical network involved in different aspects of the precision grip. When subjects applied a small grip force in comparison to a larger gripforce, activity in secondary sensorimotor related areas in the frontal and parietal lobes increased. Our result suggests that these areas play an important role in the control of fine precision grip forces in the range typically used in manipulation of small objects. We also observed increased activity in a small area of the right intraparietal cortex when the subjects coordinated the grip and the load forces in an attempt to lift a fixated object. This is the first evidence for involvement of the posterior parietal cortex in the sensorimotor control of coordinated grip and lift forces in manipulation.We applied a system identification approach to model the biomechanical system. A new technique was presented, common subsystem identification, with which the common mathematical factors in two models, identified using data from functionally different experiments, was estimated. It is concluded that these factors represent the common subsystem, here the grip force generator, involved in the experiments. The characteristics of the identified model were in agreement with experimental data on human neuromuscular grip force dynamics.The model was then extended to include wrist movement, and the consequent lift force from the frictional interaction with an object. Predictions of the motor commands (control signals) could then be formed by feeding human data through the inverted model. Hence, the motor commands used in response to an unexpectedly low friction at the grip surface, could be estimated. In agreement with recordings from neurons in the primary motor cortex of the monkey, a sharp burst in the estimated motor command for the gripforce efficiently arrested any slip. The results further indicate a state dependent control system that uses a small set of efficient corrective commands.The predicted motor commands was also compared with those theoretically optimized, with respect to minimum variance in fingertip forces. This was based on the suggestion that signal-dependent noise in the motor command influences movement control (Harris and Wolpert, 1998). We show, for the first time, that minimization of the gripforce variance, due to signal-dependent noise, indeed explains the characteristic motor commands and force profiles of a voluntary precision grip, as well as the motor command for an automatic grip force correction due to a slip.List of scientific papersI.

Binnenstedelijk ontwikkelen moet op alle fronten anders
Binnenstedelijke (her)ontwikkeling moet vraaggerichter, goedkoper, flexibeler en sneller, anders loopt de stedelijke vernieuwing compleet vast. Ook ambities vergen aanpassing.

Practicum, net even anders
Practicum; dertig leerlingen doen in vijftig minuten allemaal dezelfde handelingen, verzamelen dezelfde data waarbij ze hopelijk tot dezelfde conclusie komen. Het practicum blijftdaarmee wel beperkt tot het zelfstandig data verzamelen en het trekken van die ene conclusie. Kan dat niet anders? Door het centraal delen van data blijft er tijd over voor een centrale discussie. In dit artikel zet ik uiteen hoe dit principe bij diverse practica toegepast kan worden.ImPhys/Practicum suppor
Partnering as a strategy to approach new markets : case Anders Inno
This thesis was done for Anders Inno Oy, a Finnish small and medium sized enterprise from Turku, interested in widening their operations by approaching international markets.
This thesis was based on the applied thesis model. The purpose of this thesis was to analyse the process of partnering as a strategy in the case of Anders Inno Oy with a strong focus on trust and commitment as part of the partnering process. The research method was to investigate and analyse the factors of commitment and trust in partnerships and implement partnering as a potential strategy for Anders Inno to approach the German markets.
The first part of this thesis was to briefly illustrate the case background and circumstances of the starting situation of the project at the time the author was assigned. The second part consisted out of discussing partnering in general, as well as the part of commitment and the relationship between trust and commitment in particular. The third part was to evaluate the partnering approach by its general adaptability to this case, distinctions in its application and matters of general application to a case.
The research process of this thesis showed that partnering can bring a lot advantages to companies when understood in the right way and implemented accordingly. The main conclusions were that partnering could be the ideal strategy for reaching previously unattainable markets. However, dependent on mutual willingness and need and therefore not always easily establish able
Anders Kristian Munk on Anthropology in Business with Matt Artz
In this episode of the Anthropology in Business podcast, Anders Kristian Munk speaks with Matt Artz about his career as a business anthropologist. The conversation covers Ander’s journey from human geography to Techno-Anthropology.Anders Kristian Munk is an anthropologist, associate professor, and the director of The Techno-Anthropology Lab at Aalborg University in Copenhagen. He holds degrees in ethnology and human geography, with a PhD from the University of Oxford, and previously worked at the SciencesPo médialab in Paris and the Danish Technical University.He is the co-author of Controversy Mapping: A Field Guide, which introduces readers to the observation and representation of contested issues on digital media
Musik som handling. Verkanalys, interpretation och musikalisk gestaltning. Med ett studium av Anders Eliassons Quartetto d'Archi
Disputationen börjar med att Anders Tykesson håller ett interpretationsseminarium kl 10.30. Medverkar gör en musikensemble från Högskolan för scen och musik. Stenhammars stråkkvartett nr 2 är i fokus. Själva disputationsakten börjar kl 13.The aim of the dissertation is to illustrate the potential musical analysis has in the
development of artistic questions with regard to the interpretation and performance
of western art music. The analyses of the dissertation focus on Quartetto
d’Archi, by the Swedish composer Anders Eliasson, and discussions of music as
action, music as emotional expression, music as motion and music as mimesis are
based on the four movements of this string quartet. The methods which are used
are the very ones the project examines, namely the analysis of and the reflection
on the musical work. The author has attempted to gain a deeper knowledge of the
work and its possible interpretations by means of a comparative study of other
music and literature within the theory of music and within philosophical thinking.
The hermeneutics of Hans–Georg Gadamer and Paul Ricoeur are significant
to the thesis. For example, the author claims that Ricoeur’s concept of interpretation,
in which understanding interacts with explanation, and where the interpreter
“appropriates” the text, could be applied to musical interpretation. References
in music, or in artworks in general, to phenomena, actions and concepts
may be explained through the concept of mimesis. Within the doctoral project,
the author has worked with chamber ensembles in the form of seminars at the
Academy of Music and Drama, the University of Gothenburg.
One of the central claims of the thesis is that the musical work opens up to the
possibilities of interpretation through its own way of being, in the way it expresses
itself in its structures. Questions of the significance of music must be posed to the
musical work itself, which answers through different categories of interpretation;
it is by means of these categories of interpretation that the meaning and significance
of a musical work can be interpreted. Four categories are presented: processual
interpretation, narrative interpretation, characterial interpretation and emotional
interpretation
Analisis Penargetan Serangan Anders Breivik di Norwegia pada Tahun 2011
Lone-wolf terrorism merupakan fenomena terorisme baru tanpa jaringan atau kelompok yang beroperasi secara sendiri. Serangan Anders Behring Breivik pada tanggal 22 Juli 2011 di Oslo dan Utøya merupakan salah satu serangan lone-wolf terrorism yang terkenal karena menghancurkan gedung-gedung distrik pemerintah di Oslo dan penembakan massal remaja di pulau Utøya. Anders Breivik memiliki target sasaran utama yakni elit politik cultural marxists/multikulturalis atau Partai Buruh karena memperbolehkan Islam datang ke Norwegia dan Eropa. Penulis tertarik untuk melihat proses penargetan yang terjadi dalam serangan Anders Breivik. Sehingga rumusan masalah dalam penelitian ini adalah “bagaimana analisis penargetan serangan Anders Breivik di Norwegia pada tahun 2011?”. Metode penelitian yang digunakan adalah metode kualitatif dengan jenis penelitiannya deskriptif. Metode pengumpulan data yang digunakan dalam penelitian ini adalah studi pustaka dan data sekunder berupa buku, jurnal, karya ilmiah, dokumen resmi, dan artikel daring. Penulis menggunakan teori kebencian oleh Robert J. Sternberg yang membantu melihat keterkaitan kebencian yang dimiliki Breivik dengan proses penargetannya. Dalam bab pembahasan penulis akan membahas terkait sejarah Islam dan dinamikanya di Norwegia, kronologi serangan 22 Juli, latar belakang hidup Anders Behring Breivik, mengidentifikasi Anders Breivik sebagai terorisme dan lone-wolf terrorism, menganalisis proses penargetan, dan menggunakan teori untuk melihat relevansi dalam kasus Anders Breivik. Dari pembahasan tersebut memperoleh kesimpulan, proses penargetan serangan Anders Breivik melalui proses yang cukup panjang dan kompleks. Banyak faktor yang mempengaruhi Anders Breivik untuk memilih target sasarannya dan perlu dedikasi tinggi untuk mengorbankan kehidupannya agar tujuan politiknya tercapai.Lone-wolf terrorism is new terrorism phenomenon without a network or group that operates independently. Anders Behring Breivik attack on 22 July 2011 in Oslo and Utøya was one of the most notable lone-wolf terrorism attack, destroying government district buildings in Oslo and the mass shooting of youths on the island of Utøya. Anders Breivik has the main target, political elite of Cultural Marxist/multiculturalist or the Labor Party for allowing Islam to come to Norway and Europe. Author is interested in seeing the targeting process that occurs in the Anders Breivik attack. Research question in this research is "how is the process of targeting the Anders Breivik attack in Norway in 2011?". The research method used is a qualitative method with a descriptive type of research. The data collection method used in this study was literature study and secondary data in the form of books, journals, scientific papers, official documents, and online articles. Author uses the hate theory by Robert J. Sternberg which helps to see the relationship between Breivik's hatred and his targeting process. In the discussion chapter, author will discuss the history of Islam and its dynamics in Norway, chronology of the July 22 attacks, life background of Anders Behring Breivik, identify Anders Breivik as terrorism and lone-wolf terrorism, analyze the targeting process, and use theory to see relevance in the Anders Breivik case. From this discussion, it was concluded that, the process of targeting Anders Breivik's attack went through a fairly long and complex process. Many factors influence Anders Breivik to choose his targets and it takes high dedication to sacrifice his life so that his political goals are achieved
