A Multipitch Analyzer Based on Harmonic Temporal Structured Clustering

This paper proposes a multipitch analyzer called the harmonic temporal structured clustering (HTC) method, that jointly estimates pitch, intensity, onset, duration, etc., of each underlying source in a multipitch audio signal. HTC decomposes the energy patterns diffused in time-frequency space, i.e., the power spectrum time series, into distinct clusters such that each has originated from a single source. The problem is equivalent to approximating the observed power spectrum time series by superimposed HTC source models, whose parameters are associated with the acoustic features that we wish to extract. The update equations of the HTC are explicitly derived by formulating the HTC source model with a Gaussian kernel representation. We verified through experiments the potential of the HTC method     

MusiKalscope: a graphical musical instrument

A new multimedia system for musical and graphical expression called MusiKalscope contains subsystems that support computer-assisted jazz improvisation (RhyMe) and kaleidoscopic imagery (the lamascope). The Graphical Musical Instrument Interface (GMII) connects these subsystems and lets performers create images and music as they play virtual drums. A functional map matches the images' mood to the music played     

锦屏一、二级电站对外交通专用公路羊房沟段边坡锚索施工

锦屏一、二级电站对外交通专用公路羊房沟段部分边坡开挖后高度为35 m,地质条件极差,多为严重风化的岩石并夹杂大量泥沙,裂隙发育。为此,设计在此类路段使用1 000 kN级预应力锚索,配合3 m长锚杆对开挖边坡进行加固。锚索的注浆体为水泥净浆,锚索体为符合“预应力混凝土用钢绞线”GB/T 5224-2003和A STM A 416-94标准生产的1 860 M Pa高强度低松弛钢绞线。介绍了该段中K 46 319.84~K 46 520.16段工程施工中的锚索施工技术。

Primary spinal T-cell rich B-cell lymphoma: a case report

During my nursing career, I remember constantly being aware of patients who needed some emotional help--those who were frightened about a forthcoming operation, those who were shocked and despairing after being given their diagnosis and prognosis, others who were down in the dumps because they couldn't go home as soon as they had hoped. There were also the 'ward clowns' who tried to make everyone laugh with their good humour and little pranks, yet felt no less anxious, worried or depressed than anyone else. Patients seem to fit into categories: the nervous ones, the depressives, the jovial types, the moaners, those who demand attention and those who shun it. I feel sure that every nurse has noticed the different 'types' of people who fill hospital beds-ordinary people who seem to take on a new persona as soon as they get into their pyjamas and become a 'patient'. Somehow, their identity gets folded up and put away in their locker along with their outdoor clothes and other reminders of the outside world.
