▣ Title : Listening to Shiny Body:In Vivo Photoacoustic Tomography

▣ Speaker

:  Chulhong Kim (POSTECH)

▣ Date

& Time : Friday, September 6 (2:00

~ 3:30pm)

▣ Place

: LG Research Building, Room #101

▣ Host

: Prof. Jin Soo Lee (Tel.

▣ Abstract :

 High-resolution

volumetric optical imaging modalities, such as confocalmicroscopy, two-photon microscopy, and optical coherence tomography, have

become increasing important in biomedical imaging fields. However, due to

strong light scattering, the penetration depths of these imaging modalities are

limited to the optical transport mean free path (~1 mm) in biological tissues. Photoacousticimaging, an emerging hybrid modality that can provide strong endogenous and

exogenous optical absorption contrasts with high ultrasonic spatial resolution,

has overcome the fundamental depth limitation while keeping the spatial

resolution. The image resolution, as well as the maximum imaging depth, is

scalable with ultrasonic frequency within the reach of diffuse photons. In

biological tissues the imaging depth can be up to a few centimeters deep.

In

this presentation, the following topics of photoacousticimaging will be discussed; (1) multi-scale photoacousticimaging systems, (2) morphological, functional, and molecular photoacousticimaging, (3) potential clinical applications, and (4) contrast agents for photoacousticimaging.

 

▣ Title : Mobile

Phone Future Direction and Next Generation HW Device

Trends   

▣ Speaker

: Tae

Moon Roh (SAMSUNG)

▣ Date

& Time : Friday, November 15 (4:00

~ 5:30pm)

▣ Place

: LG Research Building, Room #101

▣ Host

: Prof. Bum Man Kim (T. 2231)

▣ Abstract :

As the rapid growth of mobile market is

coming to an end, competition between the mobile phone developing/manufacturing

companies, becomes more fierce.

Only a few companies which have both

strong brand power and the advanced technology which can satisfy the

differentiated customer needs, take the most part of market share.

In order to survive in the market change,

mobile phone manufacturers have been expanding their business areas, with the

support of their core technology.

Also, future mobile technology which can

satisfy the changed customer’s needs, due to the mobile trend paradigm

shift (Strengthening and expanding the human ability) has been developed

faster.

I would like to present and share

the vision of next generation mobile industry, through the future direction and

technology of mobile device’s HW key components such as display,

camera, connectivity, battery, and sensors.  

▣ Title : Nano-Molecular Communications : When Shannon Meets Feynman

▣ Speaker

: Chan-Byoung Chae (Yonsei University)

▣ Date

& Time : Friday, November 22 (2:00

~ 3:30pm)

▣ Place

: LG Research Building, Room #101

▣ Host

: Prof. Joon Ho Cho (T. 2377)

▣ Abstract :

Nano-molecular

communication represents, in terms of its scale and energy consumption, a very

powerful future communication system. Though nanocommunication can also be realized with electromagnetic waves, as in

traditional communication systems, such means still pose several problems, such

as the development of nano-scale

actuator, antennas, or body absorption of terahertz band frequency. Nano-molecular,

or molecular communication, however, can utilize intra-body biomoleculesthat enable a great deal of various applications.

As

research into this field has been underway for less than a decade, it calls for

fundamental intellectual challenges through preliminary studies. Thus I will

introduce some theoretical results as well as our test-bed to verify the

theoretical concepts.

▣ Title : Design Methodologies for Advanced Mobile

SOCs 

▣ Speaker

▣ Host

: Prof. Young Hwan Kim (T. 2227)

▣ Abstract :

With

advent of advanced process technology such as finFETand ever-increasing performance and functionalities of mobile SOCs, we are

facing great challenges in every way, from process to design. As we overcome

many of these challenges in Samsung’s

recent products, many of the design automation solutions or methodologies had

to be invented and breakthrough had to be made in its search for high

performance and low power / thermal.

 

In

this talk, I will present the new challenges that we are facing in the advanced

process and high-performance SOC products. Also, I will provide a glimpse into

Samsung’s

novel design methodologies being developed for addressing those new challenges.

Finally, I will introduce Infrastructure Design Center (IDC) and Design

Technology (DT) team in System LSI business of Samsung Electronics, which have

enabled the new technologies for Samsung’s

advanced products.

▣ Title : Exploiting parallelism in processing

large scale multi-dimensional datasets

▣ Speaker

: Beomseok Nam (UNIST Assistant Professor)

▣ Date

& Time : Friday, March 22 (2:00 ~ 3:30pm)

▣ Place

: LG Research Building, Room #101

▣ Host

: Prof. Sungjoo Yoo  (Tel. 2379)

▣ Abstract :

This

talk will present two different ways of exploiting parallelism in processing

large-scale multi-dimensional datasets.  The general purpose computing on

graphics processing unit (GP-GPU) has emerged as a new cost effective parallel

computing paradigm in high performance computing research that enables large

amount of scientific data to be processed in parallel. A common access pattern

into such scientific data analysis applications is multi-dimensional range

query, but inherently multi-dimensional indexing trees such as R-Trees are not

well suited for GPU environment because of their irregular tree traversal

patterns. Traversing irregular tree search path makes it hard to maximize the

utilization of massively parallel processing units in GPU. In this talk, I

would introduce two novel R-tree traversal algorithms for traversing

multi-dimensional indexes, which convert recursive access to sequential access

into hierarchical tree nodes.

 The

second half of this talk would discuss how to leverage cached data in

distributed cache infrastructure using task parallelism.  As more servers are added to distributed and

parallel systems, larger memory space becomes available for caching data

objects. However the cached objects are dispersed and traditional query

scheduling policies that take into account only load balancing do not

effectively utilize the increased cache space. This talk would introduce and

compare batch job scheduling policies that employ statistical prediction

methods and probability distribution estimations derived from recent queries in

order to improve both load balancing and cache hit ratio in shared-nothing

environment.

▣Title : 엔지니어의 business world에서의 career도전

▣Speaker : Ph.D.Junghoon Lee(베인&컴퍼니코리아)

▣Date&Time : Friday, March 29 (2:00~3:30)

▣Place : LG Research Building Room #101

▣Host : 컴퓨터공학과, 전자과, ITCE, CITE

▣Abstract : 약간 건조하게 표현하자면, 엔지니어들은 대체로 개개인의 career 개발에 있어서 타 전공자 대비 관심의 폭과 깊이가 적다. 그 결과 대체로 엔지니어의 career path는 단조로운 편이다. 그 근본원인 중 하나로, 강의자는 엔지니어들의 다양한 엔지니어링 외적인 career에 대해 지식이 부족함을 꼽고자 한다. 금번 강의에서는 다양한 career option을 미래의 공학도들에게 제시하고자 하며, 그 중에서도 business world를 대상으로 여러 career option을 제시하고 interactive하게 토론한다.

▣ Title : Pedestrian

Navigation Techniques for Smartphone Users

▣ Speaker

: Prof. ChangookPark

▣ Date

& Time : Friday, April  26 (2:00

~ 3:30pm)

▣ Place

: LG Research Building, Room #101

▣ Host

: Prof. Sangchul  Won  (Tel. 2221)

▣ Abstract :

The

demand for navigating a user with a hand-held device, especially in GPS

degraded and denied environments such as indoors and in urban canyons, has

tremendously increased over the last few years. Smartphones are attractive platforms for navigation

systems due to their small size, low cost and diversity of sensors feasible for

positioning. Most of such smartphones are equipped with GPS chip, MEMS sensors (including accelerometers,

gyroscopes, magneto-meters and barometers) along with other gadgets such as

camera and Wi-Fi. In the current state of the art in MEMS technology, the

accuracy of the inertial sensors is not good enough for getting position

information by integration of the sensor outputs over longer durations of time.

Thus MEMS based pedestrian navigation exploits the kinematics of human walk

using the inertial sensor data in a different way than the classical double

integration of acceleration in traditional Inertial Navigation Systems (INS).

The observation from all of these navigation sources should be also fused

together using Kalman filters. In this talk, various emerging

navigation technologies for pedestrian will be introduced.
